The legal priority one road user has to proceed through a crossing or intersection before others. It is set by signs, signals, or rules such as yielding to the vehicle already in the intersection.

Related: Yield sign, Pedestrian crossing
Speed limit

The maximum lawful speed allowed on a given road or area, set by law or shown on posted signs. Driving faster than this is an offense and greatly raises crash risk.

Overtaking

Passing a slower vehicle by moving into an adjacent lane or the opposite lane and pulling ahead of it. It must be done only where legal, with clear visibility and enough space.

Related: Double solid yellow line, Right of way
Reckless driving

Operating a motor vehicle with deliberate disregard for traffic laws and the safety of people and property, such as racing, weaving through traffic, or speeding in crowded areas.

Related: Speed limit, Demerit points
Driving under the influence

Operating a vehicle while impaired by alcohol, drugs, or similar substances. Impairment slows reaction time and judgment, and it is a criminal offense under Philippine law.

Related: Reckless driving, Demerit points
Demerit points

Points recorded against a driver's license for traffic violations. Accumulating enough points within a set period can lead to suspension or revocation of the license.

Related: Reckless driving, Driving under the influence
Stop line

A solid white line painted across a lane at an intersection or pedestrian crossing. Vehicles must stop before it whenever a signal, sign, or traffic enforcer requires them to halt.

Related: Traffic light, Pedestrian crossing
Yield sign

A downward-pointing triangular sign that requires drivers to slow down and give way to traffic on the intersecting road, stopping only when necessary to avoid a collision.

Related: Right of way, Stop line
Solid white line

A continuous white lane marking that separates lanes or marks the edge of the roadway. Drivers should not cross it, because it marks a place where lane changing is unsafe.

Related: Double solid yellow line, Overtaking
Double solid yellow line

Two continuous yellow lines separating traffic moving in opposite directions. Crossing them to overtake or turn is prohibited because visibility and available space are limited.

Related: Overtaking, Solid white line
Pedestrian crossing

The marked part of the roadway where people on foot are meant to cross. Drivers must slow down and give way to pedestrians who are using or about to use it.

Related: Right of way, Stop line
Hazard lights

Flashing lights at all four corners of a vehicle, used to warn others of danger such as a breakdown or very poor visibility. They are not a license to park illegally.

Related: Early warning device, Low-visibility driving
Traffic light

An illuminated signal controlling traffic at intersections. Red means stop, green means go only when the way is clear, and yellow warns that the light is about to turn red.

Related: Stop line, Right of way
Defensive driving

A way of driving that anticipates mistakes by other road users and avoids crashes even when the driver is not at fault, using alertness, space, and timely action.

Related: Three-second rule, Blind spot
Three-second rule

A guide for keeping a safe following distance: stay at least three seconds behind the vehicle ahead in good conditions, and allow more when roads are wet or visibility is poor.

Related: Tailgating, Defensive driving
Blind spot

The area around a vehicle that cannot be seen through the mirrors. Drivers must turn their head or use aids to check it before changing lanes, turning, or reversing.

Related: Defensive driving, Overtaking
Seat belt

A strap device that holds occupants in place during a sudden stop or crash, reducing injury. Philippine law requires both front and rear occupants to wear one.

Related: Defensive driving
Tire tread depth

The height of the rubber pattern on a tire's surface. Worn tread reduces grip, especially on wet roads, so tires must be replaced before the pattern becomes too shallow.

Related: Hydroplaning, Tire pressure
Tire pressure

The amount of air inside a tire, measured in psi or kPa. Correct pressure, checked while tires are cold, improves grip, fuel use, and tire life.

Related: Tire tread depth, Tire blowout
Engine oil

Lubricating fluid that reduces friction and wear inside the engine and helps carry away heat. Its level is checked with a dipstick and it must be changed regularly.

Related: Radiator coolant, Brake fluid
Radiator coolant

A mixture of water and antifreeze that circulates through the engine to control its temperature. A low coolant level can cause overheating and serious engine damage.

Related: Engine oil
Brake fluid

Hydraulic fluid that carries pressure from the brake pedal to the brakes. If the level drops or the fluid is old, braking can become weak or fail completely.

Related: Emergency braking, Engine oil
Early warning device

A pair of reflective triangular signs that a driver must set on the road when a vehicle breaks down, to warn approaching traffic and help prevent collisions.

Related: Hazard lights, Tire blowout
Anti-lock braking system

An electronic system that rapidly releases and reapplies brake pressure so the wheels do not lock, letting the driver keep steering while braking hard.

Related: Emergency braking, Skid
Hydroplaning

A loss of contact between tires and road when a layer of water builds under them. Grip and steering disappear, so the driver should ease off the accelerator without sudden braking.

Related: Tire tread depth, Skid
Skid

Sliding of the tires on the road surface caused by braking too hard, accelerating too fast, or turning sharply on a slippery surface, resulting in loss of control.

Related: Hydroplaning, Emergency braking
Tire blowout

A sudden loss of air pressure in a tire while driving. The driver should grip the steering wheel firmly, ease off the accelerator, and avoid hard braking until the vehicle slows.

Related: Early warning device, Emergency braking
Low-visibility driving

Driving in fog, heavy rain, or darkness when it is hard to see the road ahead. Drivers should slow down, use the correct lights, and increase following distance.

Related: Hazard lights, Three-second rule
Emergency braking

Applying the brakes as hard as possible to stop quickly when a hazard suddenly appears. With ABS, the driver presses firmly and keeps steering instead of pumping the pedal.

Related: Anti-lock braking system, Skid
Road courtesy

Related: Road rage, Right of way
Road rage

Aggressive behavior by a driver, such as shouting, threats, or dangerous maneuvers, triggered by anger at other road users. It escalates conflict and causes crashes.
