Question 1Road rules, traffic signs, signals and road markings

What does a circular sign with a red border and a white background generally indicate?

  1. A mandatory instruction
  2. A motorway information point
  3. A warning of a hazard ahead
  4. A prohibition or restriction Correct answer.

Explanation

In the Vienna Convention system used in Latvia, circular signs with a red border restrict or prohibit the action shown inside. Warning signs are triangular with a red border, and mandatory signs are circular with a blue background.

Question 2Road rules, traffic signs, signals and road markings

A triangular sign with a red border and a symbol of children inside warns the driver about what?

  1. A school or playground where children may cross Correct answer.
  2. A pedestrian zone closed to vehicles
  3. A bus stop lay-by ahead
  4. A compulsory route for cyclists

Explanation

Triangular red-bordered signs are warnings. The children symbol warns of a place where children are likely to be on or near the road, such as near a school, so speed should be reduced and the driver should be ready to stop.

Question 3Road rules, traffic signs, signals and road markings

What is the meaning of a circular blue sign showing a white bicycle?

  1. Cycles only: the route is compulsory for cyclists Correct answer.
  2. A cycle repair facility is nearby
  3. Cyclists must give way to motor vehicles
  4. Cyclists are prohibited beyond this point

Explanation

Blue circular signs give mandatory instructions. A white bicycle on a blue circle marks a route that cyclists must use and that other traffic generally may not use.

Question 4Road rules, traffic signs, signals and road markings

A traffic light shows a steady amber (yellow) light with no arrow. What must a driver do?

  1. Sound the horn and proceed
  2. Stop, unless it is unsafe to do so Correct answer.
  3. Continue at the same speed
  4. Reverse out of the junction

Explanation

A steady amber means the signal is about to turn red, so a driver must stop unless stopping suddenly would risk a collision. It is not a signal to accelerate through the junction.

Question 5Road rules, traffic signs, signals and road markings

What does a single broken white line in the centre of the carriageway mean?

  1. You must never cross it
  2. You may cross it when it is safe to do so Correct answer.
  3. It marks the edge of the carriageway
  4. It marks a bus-only lane

Explanation

A broken white centre line separates traffic travelling in opposite directions and may be crossed for overtaking or turning when it is safe. A solid line imposes a stricter restriction on crossing.

Question 6Road rules, traffic signs, signals and road markings

A driver approaches a pedestrian crossing where a pedestrian is waiting to cross. What is required?

  1. Slow down and give way to the pedestrian Correct answer.
  2. Continue if no traffic is behind
  3. Sound the horn to warn the pedestrian
  4. Pass the pedestrian at normal speed

Explanation

At a marked pedestrian crossing, drivers must give way to pedestrians who are crossing or clearly waiting to cross. Approaching drivers should reduce speed and be prepared to stop.

Question 7Road rules, traffic signs, signals and road markings

What does a red traffic light with a green arrow pointing left permit?

  1. Proceeding straight ahead as well
  2. Turning left without checking other traffic
  3. Ignoring the red light entirely
  4. Proceeding in the direction of the arrow after yielding Correct answer.

Explanation

A green arrow on a red signal allows movement only in the arrow's direction, and only after giving way to traffic and pedestrians that have priority. The red light still applies to all other movements.

Question 8Road rules, traffic signs, signals and road markings

On a road with a continuous white line on your side and a broken line on the other side, what applies to you?

  1. You may not cross or straddle the line Correct answer.
  2. You may cross it to turn left
  3. You may cross it to park
  4. You may cross it to overtake

Explanation

Where the line nearest the driver is continuous, that driver must not cross or straddle it. The broken line on the opposite side permits drivers travelling the other way to cross when safe.

Question 9Road rules, traffic signs, signals and road markings

What does a sign showing a red circle with a white horizontal bar mean?

  1. Stop and give way
  2. No entry for vehicular traffic Correct answer.
  3. No parking
  4. End of all restrictions

Explanation

The red circle with a white horizontal bar is the no-entry sign, meaning vehicles may not proceed past it. It is often placed at the exit of one-way roads to prevent wrong-way entry.

Question 10Road rules, traffic signs, signals and road markings

A driver is in a lane marked with a white arrow pointing straight ahead but wishes to turn right. What should the driver do?

  1. Continue straight and find a legal route to the destination Correct answer.
  2. Reverse to change lanes
  3. Stop in the lane and wait for a gap
  4. Turn right from the straight-ahead lane

Explanation

Lane arrows are mandatory and direct traffic in the indicated direction. A driver who needs to turn should follow the lane and re-route legally rather than turning from a lane that does not permit it.

Question 11Road rules, traffic signs, signals and road markings

What is the general speed limit on rural roads outside built-up areas in Latvia unless signs state otherwise?

  1. 70 km/h
  2. 90 km/h Correct answer.
  3. 50 km/h
  4. 110 km/h

Explanation

Outside built-up areas the default limit for cars and similar vehicles is 90 km/h unless signs indicate otherwise. Higher limits apply only on specific roads marked for them.

Question 12Road rules, traffic signs, signals and road markings

What is the default speed limit in built-up areas in Latvia unless signs indicate otherwise?

  1. 40 km/h
  2. 60 km/h
  3. 50 km/h Correct answer.
  4. 30 km/h

Explanation

The general limit in built-up areas is 50 km/h unless a sign sets a different figure. Lower limits may be posted near schools, hospitals or residential zones.

Question 13Road rules, traffic signs, signals and road markings

At an unmarked crossroads of equal importance, which vehicle has priority?

  1. The vehicle approaching from the left
  2. The larger vehicle
  3. The vehicle approaching from the right Correct answer.
  4. The vehicle travelling fastest

Explanation

At an intersection where the roads are of equal status and no signs or signals give priority, drivers must yield to vehicles approaching from their right.

Question 14Road rules, traffic signs, signals and road markings

A driver approaches a STOP sign at a junction. What is required?

  1. Stop only if another vehicle is visible
  2. Slow down and continue if the road looks clear
  3. Sound the horn and proceed
  4. Come to a complete stop and give way before proceeding Correct answer.

Explanation

A STOP sign requires a full stop at the stop line or, if none, at the edge of the junction, followed by giving way to traffic on the priority road. Rolling slowly past the sign does not satisfy the requirement.

Question 15Road rules, traffic signs, signals and road markings

What does a yellow diamond-shaped sign with a white border indicate?

  1. Warning of a slippery surface
  2. Compulsory direction of travel
  3. Priority road: traffic on this road has right of way Correct answer.
  4. End of priority road

Explanation

The yellow diamond marks a priority road, telling drivers that they have right of way at approaching intersections. The same shape with a diagonal bar marks the end of that priority.

Question 16Road rules, traffic signs, signals and road markings

A driver hears a siren and sees a flashing blue light approaching from behind. What should the driver do?

  1. Brake sharply in the lane
  2. Stop immediately wherever they are
  3. Accelerate to stay ahead
  4. Pull over safely and let the emergency vehicle pass Correct answer.

Explanation

Drivers must make way for emergency vehicles using blue lights and sirens by moving aside or stopping safely where possible. Sudden braking or stopping in a live lane creates additional danger.

Question 17Road rules, traffic signs, signals and road markings

What does a flashing amber light at a pedestrian crossing mean?

  1. Proceed without checking for pedestrians
  2. Give way to pedestrians on the crossing Correct answer.
  3. The crossing is out of service
  4. Stop and wait until the light turns green

Explanation

A flashing amber signal at a pedestrian crossing means drivers must yield to pedestrians on the crossing but may proceed once it is clear. It does not require a full stop if no one is crossing.

Question 18Road rules, traffic signs, signals and road markings

A solid white line marks the edge of a bus lane during operating hours. When may a car use the lane?

  1. At any time if traffic is heavy
  2. Never, under any circumstances
  3. Only when overtaking
  4. Only where signs or markings permit, such as for turning Correct answer.

Explanation

Bus lanes are reserved for the vehicles shown on the signs during the stated hours. Other vehicles may enter only where signs or markings expressly allow it, for example to turn or access premises.

Question 19Road rules, traffic signs, signals and road markings

What is the meaning of a sign showing a red circle with a car and a motorcycle side by side?

  1. No overtaking by cars
  2. No motor vehicles other than motorcycles without sidecars Correct answer.
  3. Cars must keep left of motorcycles
  4. Motorcycles must use the shoulder

Explanation

This prohibition sign bans motor vehicles generally while permitting solo motorcycles, which are shown separately. It is not about overtaking or lane position.

Question 20Road rules, traffic signs, signals and road markings

When do dipped headlights need to be used during the day?

  1. Never, if the sun is shining
  2. Only on motorways
  3. When visibility is reduced, such as in rain or fog Correct answer.
  4. Only when towing a trailer

Explanation

Dipped headlights are required whenever visibility is significantly reduced by weather or lighting conditions. They help other road users see the vehicle and are not limited to motorways or towing situations.

Question 21Road rules, traffic signs, signals and road markings

A driver intends to turn right at a junction. What is the correct sequence?

  1. Mirror, signal, manoeuvre, giving way to oncoming traffic Correct answer.
  2. Signal, accelerate, turn
  3. Turn first, then signal
  4. Sound the horn, then turn

Explanation

The standard routine is to check mirrors, signal the intention in good time, position correctly and complete the turn while yielding to oncoming traffic and pedestrians. The horn is not part of a normal turn.

Question 22Road rules, traffic signs, signals and road markings

What does a sign with a red diagonal bar across a blue circle containing a pedestrian symbol mean?

  1. Pedestrians prohibited
  2. End of a pedestrian zone or path Correct answer.
  3. Start of a pedestrian zone
  4. Pedestrian crossing ahead

Explanation

A diagonal bar across a blue circular sign marks the end of the mandatory condition shown. Here it ends the pedestrian zone or path that the blue sign began.

Question 23Road rules, traffic signs, signals and road markings

A driver is following a large lorry that obscures the traffic lights ahead. What is the safest action?

  1. Rely on the lorry driver's judgement
  2. Increase the gap so the signals become visible Correct answer.
  3. Overtake immediately regardless of markings
  4. Follow closely to see through the lorry's windows

Explanation

A larger following distance restores the driver's line of sight to signals and signs and provides stopping room. Close following behind a tall vehicle hides signals and reduces reaction time.

Question 24Road rules, traffic signs, signals and road markings

What is the meaning of a rectangular blue sign showing a white 'P' with a red diagonal bar?

  1. Parking for permit holders only
  2. Park and ride terminal
  3. Parking permitted
  4. No parking Correct answer.

Explanation

The letter P with a red diagonal bar is the no-parking sign, meaning vehicles may not park there, though stopping to set down passengers may be allowed unless otherwise indicated.

Question 25Road rules, traffic signs, signals and road markings

At a roundabout marked with a give-way line and triangle, who has priority?

  1. Traffic entering from the right
  2. Traffic entering from the left
  3. Traffic already on the roundabout Correct answer.
  4. The largest vehicle approaching

Explanation

Where a roundabout is marked with give-way signs and lines, entering drivers must yield to traffic already circulating. Once on the roundabout, a driver has priority over new entrants.

Question 26Road rules, traffic signs, signals and road markings

What must a driver do when a traffic officer raises an arm vertically at an intersection?

  1. Slow down and sound the horn
  2. Proceed only if turning right
  3. Stop immediately in all directions Correct answer.
  4. Continue driving without changes

Explanation

A vertical arm signal from a traffic officer means stop for all traffic approaching from any direction, unless the stop would endanger other road users. Drivers must obey the officer's signals even if traffic lights or signs indicate otherwise.

Question 27Road rules, traffic signs, signals and road markings

What does a circular sign with a red border and the number 50 inside indicate?

What does a triangular sign with a red border and a symbol of two children running mean?

  1. School or children crossing ahead Correct answer.
  2. No entry for pedestrians
  3. Pedestrian zone begins
  4. Playground ahead

What does a white arrow painted on the road surface in your lane indicate?

  1. The lane will end shortly
  2. The lane is reserved for buses
  3. You must follow the direction shown Correct answer.
  4. You may change lanes freely

Explanation

A white arrow on the road is a lane-use marking that shows the mandatory direction for traffic in that lane. Drivers must follow the arrow's direction when proceeding through the junction.
