Driving at night is not as easy as driving during the day, but it's not always possible to avoid it. The most important sense to a driver is vision, and that is reduced significantly after sundown. The lack of light impacts our depth perception, our peripheral vision and our colour recognition abilities. Furthermore, most people tend to feel more tired at night, specially at times when they would usually be asleep. Here are some important tips to keep in mind when driving a car at night.
Dipped/Full Beam Highlights - Highlights allow you not only to see what's ahead, but also make it easier for others to see you. They should be used not only at night, but also at dusk and dawn, in bad weather, in tunnels, or when required by law to be used during the day. Dipped highlights give you about 30 meters of visibility ahead, while full beam give you around 100 meters. In urban areas - where there are usually street lights - stick to using dipped highlights. If you're driving in unlit roads, full beam highlights may be appropriate, but only if there is no other traffic, since otherwise you'll blind other drivers.
Cleanliness is next to godliness - Make sure all the headlights and windows are cleaned, so as not to impair your vision further.
Speed - At night it's harder to tell things like speed and distance. Furthermore, our reactions may be slower than they would otherwise be due to tiredness. As such, you should drive more slowly than during the day. Rule of thumb is, you should be able to stop the vehicle in the distance at which you can see ahead.
Pedestrians - You shouldn't simply be aware of other vehicles. Pedestrians are far harder to see, since they don't have headlights. Be particularly mindful of pedestrian crossings, and reduce your speed even if you don't see someone about to cross the road.
Schedule breaks - Take as many breaks as you feel is necessary to stay alert. Eat some snacks, get some exercise. If you feel like you're starting to get tired, ask someone else to drive. If that is not a possibility, stop somewhere for the night.
