What this topic is really about
When a vehicle tailgates you, safely change lanes or pull over and increase your following distance.. Brake-checking a tailgater is dangerous and can trigger a rear-end collision you may be liable for.
The three-second rule means you should be able to count three seconds between when the vehicle ahead passes a fixed point and when you reach it. This gives adequate time to react and brake. In rain, fog, or other poor conditions, the gap should be increased to four seconds or more.
