Stop sign meaning

Octagonal red sign requiring a complete stop with wheels stationary at the stop line, or at the edge of the intersecting road if no line exists, yielding to priority traffic.

Give way triangle

Inverted red-bordered white triangle meaning slow down and yield to approaching traffic; a full stop is needed only when traffic is actually coming.

Solid white centre line

A continuous white line that must not be crossed or straddled; it marks a section where overtaking is too dangerous to permit.

Priority to the right

Default rule at unsigned junctions: yield to vehicles approaching from your right. It applies unless signs or markings establish a priority road.

Entering from a private road

A driver leaving a driveway, garage, track or unpaved path must yield to all traffic already on the public road, including cyclists and pedestrians.

Two-second rule

Minimum dry-weather following gap: count two seconds from when the vehicle ahead passes a fixed point. Reaching it sooner means you are too close.

Stopping distance formula

Stopping distance equals reaction distance plus braking distance. Reaction distance rises with speed; braking distance rises with the square of speed.

Wet-road following gap

In rain or on gravel the two-second gap doubles to four seconds, and speed must be reduced before the slippery section rather than on it.

Overtaking on the left

Default overtaking side. A right-side pass is allowed only when the vehicle ahead signals and is positioned to turn left and there is room.

Mirrors, signal, manoeuvre

Standard sequence before any turn, lane change or pull-out: check mirrors, give the signal, then move; cancel the signal afterwards.

Returning after overtaking

Move back to the right only when the overtaken vehicle is visible in the interior mirror, so you do not cut in and force it to brake.

Pedestrian crossing priority

At a marked crossing, pedestrians on it or stepping onto it have priority. Stop before the crossing line and never overtake a vehicle stopped there.

Cyclist passing clearance

Leave at least about one metre of lateral space when overtaking a cyclist or motorcyclist in built-up areas, and more at higher speeds.

Dipped headlights use

Required at night and in rain, dust or fog. Main beam is used only when it will not dazzle, and must be dipped for oncoming or followed vehicles.

Tyre tread function

Tread channels water away from the contact patch. Worn tread raises aquaplaning risk on wet roads and lengthens braking distance.

Warning triangle placement

Place the triangle behind the vehicle at a distance that gives approaching traffic time to react, and wear a reflective vest when outside at night.

Alcohol and reaction time

Alcohol slows reaction time and impairs speed and distance judgment before the driver feels affected, so the only safe driving limit is zero.

Only cure for fatigue

Rest or sleep. Coffee, fresh air and loud music mask the symptoms of drowsiness without restoring alertness or reaction time.

Medicine and driving

Antihistamines, sedatives and some painkillers cause drowsiness. Check the label and do not drive when the medicine carries a drowsiness warning.

Compulsory third-party insurance

Liability insurance covering injury and damage you cause to others is compulsory. Driving uninsured is an offence and leaves you personally liable.

Documents carried in vehicle

Keep the driving licence, vehicle registration document and proof of insurance in the vehicle and produce them when authorities request them.

Reporting an injury accident

An accident involving injury or a third party must be reported to the police. Leaving the scene of an injury accident is a serious offence.

Scene protection order

Stop, switch on hazard lights, place the warning triangle and move people away from traffic before giving first aid to casualties.

Moving an injured person

Do not move a casualty unless there is immediate danger such as fire, traffic or a fuel leak; movement can worsen a suspected spinal injury.

Chest compression rate

If a casualty is not breathing normally, compress the centre of the chest roughly 100 to 120 times per minute until help arrives.

Defensive driving definition

Assuming other road users may make mistakes and keeping a space margin that lets you avoid the consequence of their error.

Coasting in neutral

Driving with the gearbox in neutral or the clutch down reduces control and does not save fuel in modern vehicles; stay in gear while moving.

Idling and fuel waste

An engine left running while stationary burns fuel and adds emissions with no benefit; switch it off when stopped for more than a short period.

Following a tailgater

Increase your own gap to the vehicle ahead so you can brake gradually instead of abruptly, giving the tailgater more time to react.

No entry sign

A red circle containing a white horizontal bar means no entry for any vehicle; a plain solid red circle prohibits all vehicles.

Roundabout priority

Traffic already circulating has priority unless a give-way line or sign says otherwise; enter only when a gap lets you without forcing others to brake.

U-turn restrictions

U-turns are prohibited on motorways, at junctions, bends, crests and pedestrian crossings, and wherever signs forbid them or others would brake.
