How to drive safely at night



The biggest difference between night driving and the day is the difference in visibility.It sounds obvious , but when driving at night, your ability to see ahead, and of other road users to see you, is reduced. Other effects caused by
reduced light levels are:

• difficulty seeing information

• contrast falls



• colours fade

• edges become indistinct

• extra strain on the eyes

Most urban roads are lighted. Move away from an urban centre, even on to a ring road, and you will find that a majority of roads have no lighting other than cats eyes – reflective studs which mark the centre of the road and, sometimes, left-hand edge too.

The first rule of driving on roads that have no lighting is –

never drive at a speed where you would be unable to stop within the distance your headlights show to be clear.

The lights on a car have two purposes: they help you see at night and they help other road users see you. You don’t have to wait for the nighttime before you turn on your car lights or for that matter until the street lights come on. If light levels dip, whatever time of day, then turn on your lights. It is certainly wise to have your lights on a dusk approaches.

Your headlights have two setting: dip and full beam. When driving at night on lit roads you should have your headlights switched to dip. A standard set of headlights will provide about 30 metres of visibility when dipped and about 100 metres when on full beam.

Urban Areas

• Always used dipped headlights when driving at night in built-up areas.

• Keep alert – pedestrians can be incredibly difficult to see.

• Approach pedestrian crossings with caution.



• between the hours of 11.30pm and 7am you must only sound your horn to avoid danger from a moving vehicle. If you need to warn other road users of your presence, you should should flash your headlights.

Full Beam Headlights

When driving on unlit roads and when no other traffic can be seen ahead of you, you should turn your headlights on full beam. When you see a vehicle, pedestrian or cyclist approaching you must turn the headlights to dip. Remember the Highway Code states – do not use any lights in a way that would dazzle or cause discomfort to other road users, including pedestrians, cyclists and horse riders.


Overtaking another vehicle whilst driving at night can be a risky endeavor. Remember, your view ahead will be limited by the darkness. Bends and dips in the road can be cloaked in darkness. These can easily hide other road users, whether cars or pedestrians. Never takes risks. Be certain that the road ahead is clear. Once you have drawn level with the vehicle you are overtaking switch your headlights to full beam if there are no other vehicles ahead of you.

If a driver overtakes you then keep your headlights on full beam until they are level with you. The extra light will help them overtake you safely. Once they pull past you turn you headlights to dip.


One of the biggest night time hazards is dazzle, caused by the light from on-coming headlights.

For newly qualified drivers, driving at night for the first few times can be a shock to the system, especially in busy traffic on unlit roads.

During the day, light is pretty well evenly distributed but at night intense light sources cut through the black making it hard on your eyes and sometimes even acting to disorientate you. This light also causes dazzle.

To avoid dazzle:

Never stare at oncoming headlights. Place your gaze slightly to the left-hand side of the road. If you are having difficulty seeing ahead you should pull over and stop.

You can be dazzled from behind, from light reflected in your interior mirror. To ease this dazzle you should adjust your interior mirror. Many modern interior mirrors have an anti-dazzle setting which can be switched to easily.

Try and anticipate when oncoming headlights may reduce your vision. If you think you’re likely to be dazzled then slow down.

Be aware that brake lights can also cause dazzle. Don’t keep your foot on the brake pedal if waiting at a junction or queuing in traffic, except in fog.


Car lights need to be cleaned regularly. Light covers that are covered in grime can prove to be ineffective. You will find it harder to see the road, and other road users will find it harder to see you.

Clean your windscreen regularly and make sure you have a good windscreen washer concentrate in your windscreen washer reservoir. A clean windscreen will reduce dazzle.

Driving at night is a skill that needs to be learnt. As learner drivers you are not required to have lessons in driving at night however, for safety’s sake, you may find it useful to ask your instructor for a few night time lessons just be sure.
