Libya Driving Theory Test key terms

An octagonal red sign with white lettering that requires a driver to bring the vehicle to a complete halt at the stop line and give way before proceeding.

An inverted triangular sign warning that drivers must slow down and let traffic on the intersecting road pass before entering or crossing it.

A solid white line painted across a lane marking the exact point where a vehicle must halt at a stop sign or traffic signal.

A dashed line along the middle of the road that may be crossed to overtake or change lanes when it is safe to do so.

An unbroken line that must not be crossed or straddled, usually marking a hazard such as a bend, crest or restricted visibility zone.

A pedestrian crossing marked by broad alternating light and dark stripes where pedestrians have priority and vehicles must stop for them.

Painted lines, arrows, hatched areas and symbols on the road surface that guide, warn and regulate drivers in addition to upright signs.

The legal entitlement of one road user to proceed first while others wait, determined by signs, signals, road markings or general priority rules.

A road whose traffic has the right to pass through intersections first, usually indicated by priority signs on the road itself and give-way signs on crossing roads.

A junction with no signs, signals or markings, where drivers must slow down, look carefully and apply general priority rules before proceeding.

A circular junction where traffic travels in one direction around a central island and entering vehicles normally give way to traffic already circulating.

The maximum legal speed permitted on a given road or zone, shown by signs or set by law, regardless of how fast the road could safely be driven.

The gap kept behind the vehicle ahead that allows enough time to stop if it brakes suddenly, commonly measured with the two-second rule.

A method of judging following distance by counting two seconds between the vehicle ahead passing a fixed point and your own vehicle reaching it.

The distance a vehicle travels from the moment the brakes are applied until it comes to a complete stop, increasing with speed and poor road conditions.

The distance travelled during the driver's reaction time before the brakes are actually applied, lengthened by fatigue, alcohol or distraction.

Passing a slower vehicle travelling in the same direction, permitted only when visibility, road markings and oncoming traffic make the manoeuvre safe.

The area around a vehicle that cannot be seen in the mirrors, which a driver must check by turning the head before changing lanes or overtaking.

Moving from one marked lane to another, requiring mirror checks, a blind-spot check, signalling and sufficient space before moving.

A flashing light on a vehicle used to signal an intention to turn, change lanes, overtake or pull out, given in good time to warn other road users.

A set of coloured lights controlling traffic flow, where red means stop, amber warns of a change and green permits movement if the way is clear.

Hand and arm signals given by a police officer controlling traffic, which override traffic lights, signs and road markings and must always be obeyed.

The skill of spotting developing risks on the road early enough to respond smoothly, such as pedestrians stepping out or vehicles emerging from side roads.

A style of driving that anticipates the mistakes of others, keeps a safety margin and avoids unnecessary risk through planning and observation.

Adjusting speed to match actual conditions such as rain, dust, darkness, traffic density or road surface, even when below the posted limit.

Loss of tyre grip on a wet road when water builds up under the tyres, causing steering and braking to become ineffective until speed is reduced.

The depth of the grooves on a tyre, which must stay above the legal minimum to maintain grip and clear water from the contact patch.

The amount of air inside a tyre, which should be checked regularly when cold because incorrect pressure harms grip, braking and fuel use.

A quick check before driving of tyres, lights, brakes, mirrors, fluids and load security to confirm the vehicle is safe to use.

The normal low-beam setting used at night and in poor visibility to light the road without dazzling oncoming drivers.

A bright main-beam setting for unlit roads that must be switched to dipped beam when another vehicle approaches or when following closely.

The official document authorising a person to drive a specified category of vehicle, which must be valid and carried as required by law.

The minimum compulsory cover that pays for damage or injury caused to other people or their property in a crash involving the insured vehicle.

The official record and plate identifying a vehicle and its owner, which must be current and clearly displayed while the vehicle is used on public roads.

A restraining strap fitted to seats that must be worn by the driver and passengers where provided, greatly reducing injury in a collision.

Immediate basic care given to an injured person before professional help arrives, focused on safety, bleeding control, breathing and keeping the person warm.

Contacting the police, ambulance or rescue service after a crash, giving the exact location, number of casualties and any continuing hazards.

A reflective folding triangle placed on the road behind a broken-down vehicle to warn approaching traffic, positioned where it can be seen in good time.

A stable side-lying posture used for an unconscious but breathing casualty to keep the airway open while waiting for medical help.
