1. Make sure your windscreen is kept cleanDid you know that dirt, dust and dead insects can limit your vision? Unfortunately they can limit what you see ahead of you and make things seem even darker. This is why it's essential to make sure that your windscreen is kept completely clean.
2. Cut your speedAs you might expect your visibility tends to be worse at night - it being dark and all.
By reducing your speed slightly you are giving yourself a little more time to react and therefore reduce the risk of having an accident (and having to make a claim on your young drivers insurance).
