Night Driving & Using Headlights Correctly

Driving in the dark requires extra care. Headlight use, judging speed and distance, and spotting hazards in low light are all skills the examiner will check on evening tests.

The full guide

Driving at night is one of the most challenging conditions you will face. Reduced visibility, glare from oncoming headlights, and difficulty judging distances all demand extra attention. The examiner may include evening or dusk driving in your test, so being prepared is essential.

The most important skill is correct headlight use. Use dipped headlights in built-up areas and when there is oncoming traffic or a vehicle ahead. Use main beam on unlit roads when no one is ahead of you, but dip them as soon as you see another vehicle to avoid dazzling the driver. If you are dazzled by an oncoming vehicle, do not brake suddenly or swerve. Look towards the left kerb or verge until the vehicle passes.

Judging speed and distance is harder at night. Oncoming vehicles may appear closer than they are because their headlights are bright and obvious. When emerging from a junction at night, take extra time to check both ways — it is harder to judge the speed of approaching vehicles in the dark.

Pedestrians and cyclists are harder to spot in low light. Watch for reflections from clothing, bicycle lights, and movement near crossings. Children and people in dark clothing are especially hard to see. Reduce your speed in areas with limited street lighting so you have more time to react.

Your eyes need time to adjust to darkness. When leaving a brightly lit area, your night vision will be reduced for several seconds. Drive more slowly until your eyes adapt. Avoid looking directly at oncoming headlights — focus on the left edge of your lane to maintain your position.

Common faults

  • Using main beam when there is oncoming traffic or a vehicle ahead
  • Not dipping headlights soon enough when meeting oncoming traffic
  • Driving too fast for visibility on unlit roads
  • Not reducing speed when dazzled by oncoming headlights
  • Failing to spot pedestrians or cyclists in dark clothing
  • Emerging from junctions without extra caution for approaching vehicles
  • Not cleaning headlights, windscreen, or mirrors, reducing visibility

What the examiner looks for

  • You use dipped headlights in built-up areas and when meeting traffic
  • You use main beam on unlit roads and dip promptly for oncoming vehicles
  • You reduce your speed on unlit roads and in poor visibility
  • You look to the left when dazzled rather than swerving or braking harshly
  • You take extra care at junctions where vehicle speeds are harder to judge
  • You spot vulnerable road users despite reduced visibility

Quick tips

  1. 1Dip your headlights as soon as you see another vehicle — do not wait until they are close
  2. 2If dazzled, look at the left kerb until the vehicle passes — never stare at the lights
  3. 3Reduce speed on unlit roads — your stopping distance is the same but your visibility is reduced
  4. 4Keep your windscreen clean inside and out — grime scatters light and reduces visibility
  5. 5Watch for pedestrians near pubs, clubs, and late-night shops — they may not be paying attention

Common questions about night driving & using headlights correctly

When should I use main beam headlights?
Use main beam on unlit roads when there is no traffic ahead of you. Dip them as soon as you see oncoming traffic or a vehicle in front. Dipped headlights are the default for built-up areas and when following or meeting other vehicles.
What should I do if I am dazzled by oncoming headlights?
Do not brake suddenly or swerve. Slow down slightly if needed, and look towards the left kerb or verge until the vehicle passes. Avoid staring at the lights — it temporarily reduces your night vision.
Can I drive with only sidelights at night?
No. Sidelights are not bright enough for safe night driving. You must use dipped headlights whenever visibility is seriously reduced, including at night. Sidelights are only for parked vehicles or very well-lit urban areas.
How do I judge the speed of oncoming vehicles at night?
It is harder at night because headlights make vehicles appear closer. Allow extra time before emerging from a junction. If you are unsure, wait. It is better to delay than to misjudge and pull out in front of a vehicle you did not see clearly.
Should I drive slower at night?
Yes, especially on unlit roads. Your visibility is reduced, pedestrians are harder to spot, and hazards like potholes or debris are invisible until you are close. Reduce your speed so you can stop within the distance you can see to be clear.
How do I maintain my night vision?
Avoid looking directly at bright lights. Keep your windscreen clean. Reduce interior lighting and dashboard brightness. Allow your eyes time to adjust when moving from bright to dark areas. Never wear tinted glasses at night.
