You need to look well ahead to make sure you have room to make these moves safely. 1  Most good drivers look 12-15 seconds ahead. That means looking ahead the distance you will travel in 12-15 seconds. 2  Look for vehicles coming onto the highway, into your lane, or turning. Watch for brake lights from slowing vehicles.
One good rule for how much space you should keep in front of you is at least 1 second for each 10 feet of vehicle length at speeds below 40 mph. At greater speeds, you must add 1 second for safety. For example, if you are driving a 40-foot vehicle, you should leave 4 seconds between you and the vehicle ahead. In a 60-foot rig, you will need 6 seconds. Over 40 mph, you would need 5 seconds for a 40-foot vehicle and 7 seconds for a 60-foot vehicle.
