1) You must begin braking sooner, particularly when you have a load.
2) You make wider right turns. For a two-axle 20′ truck, you should begin your turn once a little more than 1/2 of your vehicle has passed the radius point of your turn (this will keep you from clipping curbs).
3) You won’t accelerate that fast, so pull into faster lanes of traffic with caution.
4) You will have a more difficult time maintaining acceleration on ascending grades and a more difficult time slowing down on descending.
5) Know the height of your truck.
6) Your truck is probably wider than the cab meaning you have to drive more in the center of the lane.
7) Make sure you adjust all your mirrors before you begin driving.
8) Make sure your load is properly placed and secured.
9) When backing into a space, take your time. You need to be about half the length of your truck away from any barriers that you have to navigate between. Begin making your turn into the space immediately at the point where you want to tires to rest when you are parked (i.e. with enough room to open both cab doors). You generally have to cut the wheel pretty hard if you have barriers on each side of you. Practice once or twice in an empty parking lot if you can, you’ll feel better about doing it when the stakes ae higher.
