But, that's not always the case. Safe following distances vary according to traffic speed and weather conditions and according to the type of vehicle you're driving. In good conditions, you should allow 2 seconds between your car and the vehicle in front of you. Here's an easy way to work that out.
Minimum parking distances at intersections, pedestrian crossings, railways and driveways. Permitted parking distances vary with the type of accessway or object. For example, while you can park 1m away from a driveway, you have to be at least 6m away from an intersection unless there are marked bays or signage saying you can park closer. Parking any closer than six metres starts to significantly restrict visibility especially if the vehicle is an SUV or van which is taller than a car.
