Tailgating is unsafe and illegal. We recommend allowing a minimum two-second gap between you and the car in front of you when driving.
To calculate the gap, pick a fixed object on the side of the road. As the back of the car in front of you passes the object, start to count. If the front of your car reaches object before you get to two, you’re travelling too close. Slow down and increase the distance between the vehicles.
You should increase the gap to greater than two seconds in wet or foggy weather, at night, if you are tired or if you are towing or driving a heavy vehicle.
Refer to rules 126 and 127 of the Victorian Road Safety Road Rules 2017.
