Quite true, and you can try it yourself if you like. Start accellerating your truck as hard as you like, then watch the speedometer and let go of the accelerator. No matter how fast the truck was accelerating as soon as you stop giving it gas it will no longer accelerate. (It will keep moving, of course, but it won't go any faster)
