Question 1Traffic signs, signals, and pavement markings
In Puerto Rico, a red octagonal sign at an intersection with the word "PARE" requires you to:
- stop only when other traffic is present
- enter only if the road is clear
- slow down and yield
- come to a complete stop Correct answer.
Explanation
A red octagon is the stop sign, and in Puerto Rico its legend is PARE. You must come to a complete stop at the stop line or before entering the crosswalk, then proceed only when safe.
Question 2Traffic signs, signals, and pavement markings
Which shape identifies a yield sign?
- An eight-sided shape
- A downward-pointing triangle Correct answer.
- A long, narrow pennant shape
- A diamond shape
Explanation
A yield sign is an inverted triangle with a red border. Drivers must slow down and give the right-of-way to traffic and pedestrians before entering.
Question 3Traffic signs, signals, and pavement markings
Most warning signs on Puerto Rico roads are:
- orange diamonds
- yellow diamonds Correct answer.
- white rectangles with black letters
- green rectangles
Explanation
Warning signs are typically yellow diamonds with black symbols or words. They alert drivers to curves, intersections, and other hazards ahead.
Question 4Traffic signs, signals, and pavement markings
A flashing red traffic signal means:
- proceed without stopping if no cars are near
- slow down and proceed with caution
- stop only during posted hours
- stop completely, then proceed when safe Correct answer.
Explanation
A flashing red signal is treated like a stop sign. Stop completely, yield to traffic and pedestrians, and proceed when it is safe.
Question 5Traffic signs, signals, and pavement markings
A solid white line between lanes traveling in the same direction means:
- lane changes are discouraged Correct answer.
- traffic moves in opposite directions
- passing is permitted
- the lane is reserved for buses
Explanation
A solid white line separates lanes moving in the same direction and discourages lane changes. A broken white line permits lane changes when safe.
Question 6Traffic signs, signals, and pavement markings
A double solid yellow center line means:
- the road is one-way
- passing is allowed only at night
- passing is allowed from both directions
- no passing in either direction Correct answer.
Explanation
Double solid yellow lines separate traffic moving in opposite directions and prohibit passing from both sides. You may cross only for a left turn into a driveway or side road where permitted.
Question 7Traffic signs, signals, and pavement markings
Green signs on a highway provide information about:
- services such as fuel and food
- destinations and distances Correct answer.
- rules that drivers must obey
- road work and construction zones
Explanation
Green guide signs give destinations, distances, and route information. They help drivers navigate rather than regulate or warn.

Orange is the standard color for construction and work-zone signs. These signs warn of workers, lane shifts, and temporary hazards.
Question 9Traffic signs, signals, and pavement markings
A broken yellow center line means:
- you must drive on the left side
- the lane is for turning only
- you may pass when it is safe Correct answer.
- passing is never allowed
Explanation
A broken yellow center line separates opposing traffic and permits passing when the way is clear. You must still obey speed limits and no-passing zones.
Question 10Traffic signs, signals, and pavement markings
A white X-shaped sign with the words "RAILROAD CROSSING" at a track means:
- the railroad tracks are no longer in use
- yield to trains and cross when clear Correct answer.
- sound your horn and drive across quickly
- stop only when a train can be seen
Explanation
A crossbuck marks a railroad crossing, and drivers must yield to trains. Because trains cannot stop quickly, cross only after confirming the track is clear.
Question 11Traffic signs, signals, and pavement markings
A five-sided (pentagon) sign is used to mark:
- an intersection where drivers must yield
- a highway construction area
- a railroad crossing with tracks
- a school zone or school crossing Correct answer.
Explanation
A pentagon-shaped sign marks a school zone or school crossing. Slow down and watch for children, especially during school hours.
Question 12Traffic signs, signals, and pavement markings
A steady red arrow pointing left means:
- wait for a green arrow before turning left Correct answer.
- the left lane is closed ahead
- left turns are allowed after slowing down
- you may turn left if no traffic is coming
Explanation
A steady red arrow is a red light for that movement. Do not turn in the direction of the arrow until a green arrow or other signal permits it.
Question 13Traffic signs, signals, and pavement markings
A flashing yellow traffic signal means:
- slow down and proceed with caution Correct answer.
- the signal is broken so turn around
- you have the right-of-way over all traffic
- stop before entering the intersection
Explanation
A flashing yellow signal does not give you the right-of-way. Slow down, check for traffic and pedestrians, and proceed cautiously.
Question 14Traffic signs, signals, and pavement markings
When a stop sign is posted with a painted stop line and crosswalk, where should you stop?
- in the crosswalk
- at the corner curb only
- after the crosswalk
- before the stop line Correct answer.
Explanation
A stop line shows the point where you must stop for a sign or signal. If there is a crosswalk, stop before the stop line so pedestrians have room.
Question 15Traffic signs, signals, and pavement markings
Blue signs along a highway generally indicate:
- the distance to major cities
- warnings about curves and hills
- services such as gas and food Correct answer.
- rules that drivers must obey
Explanation
Blue signs indicate motorist services such as fuel, food, lodging, and hospitals. They are not regulatory or warning signs.
Question 16Traffic signs, signals, and pavement markings
A white arrow painted in a lane and pointing straight ahead means:
- you may turn right from that lane
- travel straight ahead in that lane Correct answer.
- you may use the lane to pass
- the lane ends a short distance ahead
Explanation
A white lane arrow shows the movement allowed from that lane. A straight arrow means you must continue straight, so do not turn from that lane.
Question 17Traffic signs, signals, and pavement markings
A white diamond symbol painted in a traffic lane indicates:
- a reserved high-occupancy lane Correct answer.
- a crossing zone for pedestrians
- a lane that is closed to all traffic

A white diamond symbol marks a lane reserved for high-occupancy vehicles or another special use. Check nearby signs for the exact restriction and hours.
Question 18Traffic signs, signals, and pavement markings
A steady yellow traffic light means:
- the light will stay yellow for one minute
- speed up to beat the red light
- stop if you can do so safely Correct answer.
- proceed because you have the right-of-way
Explanation
A steady yellow light warns that the signal is about to turn red. Stop if you can do so safely; if you are already in the intersection, clear it.
Question 19Traffic signs, signals, and pavement markings
On a divided highway, the left edge of the roadway is usually marked with:
- a yellow line Correct answer.
- a white line
- no line at all
- a red line
Explanation
Yellow lines separate traffic moving in opposite directions and mark the left edge of divided highways. White lines mark the right edge and lanes moving the same way.
Question 20Traffic signs, signals, and pavement markings
Your side of a center line is solid yellow, while the other side is broken yellow. What does this mean?
- passing is prohibited from your side Correct answer.
- the road is one-way in your direction
- passing is allowed from your side only
- passing is allowed from both sides
Explanation
A solid yellow line on your side means you may not pass. The broken line on the other side allows passing for traffic coming from the opposite direction when safe.
Question 21Traffic signs, signals, and pavement markings
A flashing yellow left-turn arrow means:
- turn left after yielding to traffic Correct answer.
- you have a protected left turn
- you must stop and wait for a green arrow
- left turns are prohibited at this signal
Explanation
A flashing yellow arrow permits the turn but does not protect it. Yield to oncoming traffic and pedestrians before turning.
Question 22Traffic signs, signals, and pavement markings
You face a green left-turn arrow while the circular signal for straight traffic is red. What may you do?
- stop and wait for a police officer
- turn left in the direction of the arrow Correct answer.
- turn left only after the circle turns green
- drive straight through the red circle
Explanation
A green arrow gives a protected right-of-way for that movement even if other lights are red. Proceed left only when the arrow is green and the path is clear.
Question 23Traffic signs, signals, and pavement markings
A center lane marked with solid yellow lines on both sides and white left-turn arrows is used for:
- parking during posted business hours
- left turns from both directions Correct answer.
- passing slower vehicles on the left
- emergency stopping only
Explanation
A center lane marked for two-way left turns is shared by traffic from both directions. Use it to begin or complete a left turn, not for passing or parking.
Question 24Traffic signs, signals, and pavement markings
At a railroad crossing with flashing red lights and no gate, you should:
- drive around the crossing if traffic is light
- cross quickly if no train is in sight
- stop only if warning bells are ringing
- stop until the lights stop flashing Correct answer.
Explanation
Flashing red lights mean a train is approaching or the crossing is active. Stop and wait until the lights stop flashing and you can see that the track is clear.
Question 25Traffic signs, signals, and pavement markings
An overhead lane-control signal showing a red X above your lane means:
- the lane is closed to traffic Correct answer.
- the lane is open but crowded
- you must stop in the lane and wait
- you may use the lane only to turn
Explanation
An overhead red X means the lane is closed and must not be used. A green arrow or green downward arrow would indicate the lane is open.
Question 26Traffic signs, signals, and pavement markings
An octagonal (eight-sided) sign is used only to:
- Show the maximum legal speed
- Mark a railroad crossing
- Warn of a sharp curve ahead
- Require a full stop Correct answer.
Explanation
The eight-sided shape is reserved exclusively for stop signs, so an octagon always requires you to come to a complete stop and yield to traffic and pedestrians before continuing.
Question 27Traffic signs, signals, and pavement markings
A yellow diamond-shaped sign generally:
- Gives orders that must be obeyed
- Warns of a hazard ahead Correct answer.
- Marks a construction zone
- Provides information about nearby services
Explanation
Yellow diamonds are warning signs. They alert you to conditions ahead, such as curves, intersections, or a narrowing road, so you can slow down and adjust your driving.
Question 28Traffic signs, signals, and pavement markings
A white rectangular sign with black lettering that shows a number is most likely:
- A warning about a hazard ahead
- A guide to a nearby city
- A speed limit sign Correct answer.
- A temporary work zone marker
Explanation
White rectangular signs with black lettering are regulatory signs that state a law, and a number on one is normally the maximum legal speed unless a different limit is posted.
Question 29Traffic signs, signals, and pavement markings
A broken (dashed) white line between two lanes of traffic means:
- You may never change lanes in that area
- The lane to your right is ending
- You may change lanes when it is safe Correct answer.
- Traffic in the two lanes moves in opposite directions
Explanation
White lines separate lanes traveling in the same direction, and a broken line means lane changes are permitted after signaling, when there is a safe gap in traffic.
Question 30Traffic signs, signals, and pavement markings
A flashing red traffic light means:
- Stop, then go when it is safe Correct answer.
- Slow down and continue without stopping
- The signal is out of order, so continue at normal speed
- Wait at the light until it turns green
Explanation
A flashing red signal works like a stop sign: come to a complete stop, yield to traffic and pedestrians, and proceed only when the way is clear.
Question 31Traffic signs, signals, and pavement markings
Two solid white lines running side by side between two lanes mean:
- You may cross only when passing a slow-moving vehicle
- The left lane is reserved for turning traffic
- Crossing the lines to change lanes is prohibited Correct answer.
- Traffic in the two lanes moves in opposite directions
Explanation
A double solid white line separates lanes going the same direction in a section where lane changes are not allowed, such as approaching an intersection or inside a tunnel.
Question 32Traffic signs, signals, and pavement markings
An overhead lane-control signal showing a yellow X above your lane means:
- The lane is closed to all traffic
- Use the lane only to prepare for a turn Correct answer.
- The lane may be used only by buses
- Traffic in the lane must reverse direction
Explanation
A yellow X means the lane is still open but is about to become a turn lane, so you should enter it only if you intend to make the turn.
Question 33Traffic signs, signals, and pavement markings
You come to an intersection where the traffic signal is dark because of a power failure and no stop sign is posted. You should:
- Stop only if another vehicle is already in the intersection
- Sound your horn and drive through carefully
- Stop and yield as at a stop sign Correct answer.
- Proceed without slowing because the light no longer controls traffic
Explanation
When a signal is not working, drivers must treat the intersection as an all-way stop: stop, then proceed in order of arrival while yielding to vehicles already in the intersection.
Question 34Traffic signs, signals, and pavement markings
A crosswalk on a roadway is marked by:
- A single broken yellow line along the curb
- Yellow diagonal stripes along the center line
- A row of white arrows pointing at the intersection
- Two parallel white lines running across the roadway Correct answer.
Explanation
Crosswalks are marked by solid white lines running across the road, sometimes with additional white blocks, and drivers must yield to pedestrians within them.
Question 35Traffic signs, signals, and pavement markings
Yellow-and-black chevron signs placed along the outside of a curve are used to:
- Guide drivers through a sharp curve Correct answer.
- Show the legal speed limit through the curve
- Show where drivers must stop before a bridge
- Mark the start of a passing lane
Explanation
Chevrons are large yellow signs with black stripes arranged to show the direction of a sharp curve; they help you judge the curve and should prompt you to slow down.
Question 36Traffic signs, signals, and pavement markings
A small yellow rectangular plaque reading "35 MPH" mounted below a curve warning sign indicates:
- A recommended speed for the curve Correct answer.
- The legal maximum speed beginning at the sign
- The legal minimum speed through the curve
- The distance in miles to the next town
Explanation
A small yellow plaque with a number beneath a warning sign gives an advisory speed, the speed judged safe for the hazard in good conditions; it is a recommendation rather than an enforceable limit.
Question 37Traffic signs, signals, and pavement markings
A round yellow sign bearing a black X and the letters "RR" means:
- A railroad crossing is ahead Correct answer.
- A gate is the only warning device there
- You are at the tracks and must stop
- The crossing has been abandoned
Explanation
This round yellow sign is an advance railroad warning placed some distance before the tracks. It tells you to slow down, look, and listen so you can stop if a train is coming.
Question 38Traffic signs, signals, and pavement markings
A line of white triangles painted across your lane at the entrance to an intersection means:
- Your lane ends and merges into the next one
- Come to a complete stop before entering
- Yield before entering the intersection Correct answer.
- You have the right of way over crossing traffic
Explanation
A row of white triangles forms a yield line. It shows where you should slow or stop and give way to traffic on the road you are about to enter.
Question 39Traffic signs, signals, and pavement markings
You face a steady green circular light while a steady red left-turn arrow is displayed at the same time. What may you do?
- Go straight, but wait for a green arrow to turn left Correct answer.
- Turn left after coming to a full stop
- Turn left because the green circular light permits all movements
- Neither go straight nor turn left until the light changes
Explanation
Each signal controls its own movement. The green circular light allows you to go straight, while the red arrow prohibits left turns until a green arrow appears.
Question 40Traffic signs, signals, and pavement markings
The word "STOP" painted in large white letters in your lane means:
- You must stop exactly where the word ends
- Traffic in the lane must merge to the left
- A stop is required ahead Correct answer.
- The lane ahead is reserved for buses
Explanation
A STOP legend painted on the pavement is an advance warning that a stop sign or signal controls the intersection ahead, so you should slow down and prepare to stop at the stop line or crosswalk.
Question 41Rules of the road and right-of-way
Two vehicles arrive at a four-way stop at the same moment from different directions. Which vehicle should proceed first?
- The larger vehicle
- The vehicle on the left
- The vehicle that is going straight
- The vehicle on the right Correct answer.
Explanation
At a multi-way stop, the first vehicle to arrive goes first. When two vehicles arrive at the same time, the driver on the left must yield to the driver on the right.
Question 42Rules of the road and right-of-way
When may you turn right at a steady red light?
- Never, unless a green arrow is showing
- After a complete stop, if no sign prohibits the turn Correct answer.

- Only when a police officer signals you to do so
Explanation
A right turn on red is allowed after a full stop unless a sign forbids it. You must yield to pedestrians and to traffic that has the green light.
Question 43Rules of the road and right-of-way
A pedestrian is crossing in a marked crosswalk at an intersection with no traffic signal. What must you do?
- Stop and wait until the pedestrian has crossed Correct answer.
- Sound your horn so the pedestrian walks faster

On a two-way street with no pavement markings, where should you drive?
- On either side, whichever is smoother
- On the right half of the roadway Correct answer.
- On the left side of the road
- Near the center of the road
Explanation
Traffic keeps to the right in Puerto Rico, so you drive in the right half of the roadway except when passing or turning.
Question 48Rules of the road and right-of-way
When may you turn left at a steady red light?
- Never, under any circumstances
- From one one-way street onto another, after stopping Correct answer.
