Your first rule when driving at night is make sure you can stop well within the distance your headlights show to be clear. Bear in mind that a standard set of headlights will provide about 30 metres of visibility when dipped and 100 metres when on full beam. Remember, you should always keep your lights dipped in lit or urban areas. You can use full beam if you’re on a straight unlit road, but when you see another vehicle approaching be considerate and turn your headlights to dip a second after they are able to see you. This shows them that you have gone on to dip, and may remind them to do the same. You should then slow down, as the distance you can see to be clear will be reduced. If no other traffic is approaching, return to full beam once the vehicle has passed you. When driving around corners and over brows, dip early before you encounter and dazzle an on-coming driver.
