that really depends on the situation. If you are following a semi trailer in your car the good rule of thumb is 3 seconds. Pick something on the side of the road... such as a tree... when the rear of the semi passes the tree count three seconds then the front of your vehicle should pass the tree. This will give you plenty of time to safely stop if need be at any speed. If the semi is following you and you feel they are too close it is advised to simply pull over or change lanes to let them pass.
