Once on the freeway, a good safety conscious driver moves at a steady speed, looking forward and anticipating what's going to happen on the road ahead. Traffic should keep to the right, using the left lanes for passing.
As in city driving, your eyes should be constantly moving, scanning the road ahead, to each side and behind. Look ahead to where you are going to be in the next 15 to 20 seconds, or as far ahead as you can see, when you travel at faster speeds. Remember to keep scanning and check your mirrors frequently. Stay clear of large vehicles. Because of their size, they block your view more than other vehicles. Leave space around your vehicle. This will let you see clearly in every direction and will give you time and space to react.
Be careful not to cut off any vehicle, large or small, when making a lane change or joining the flow of traffic. It is dangerous and illegal for a slower moving vehicle to cut in front of a faster moving vehicle.
Use the far left lane of a multi-lane freeway to pass traffic moving slower than the speed limit, but don't stay there. Drive in the right-hand lane when possible. On many freeways with three or more lanes in each direction, trucks cannot travel in the far left lane and must use the lane to the right for passing. Get into the habit of driving in the right lane, leaving the other lanes clear for passing.
