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.
A common guideline is that after each typical drink, you must wait 45 minutes before attempting to drive. If you have another drink, you must add another 45 minutes. You've had a drink and must wait 45 minutes before driving. A quarter hour later, you have another drink. Now you must wait 45 minutes PLUS the 30 minutes left over from the first drink. That's one and a quarter hours before you should drive.
