For any newly paved driveway, it is important to wait at least 3 days before you drive on it. If the temperature outside is 20Â°C or more, it would be advisable to wait for a longer period of time. Once your driveway has had a chance to cure, it is important that you remember to not turn the wheels of your vehicle sharply on hot days. When you do drive on the driveway, make sure the vehicle is in motion when turning the wheels. You can help your driveway cure by watering it with a garden hose.
How far in advance should you signal before making a turn When driving in residential areas you should signal around 30 meters (100 feet) in advance of making a right or left turn. This is assuming there are no other turns on the same side of the road before the turn you intend on taking, else you will need to signal after this turn.
