One thing I was told a long time ago that has worked for me, play out situations while you’re driving, and then think about the proper actions to take. Do this repeatedly and it will become reactionary when it really happens. For instance since you’re driving a truck, what actions need to take place when you blow a steer. No brakes, hammer the gas pedal, grip the wheel, very gently start decreasing speed, when it happens you won’t have much time to think, if you hit your brakes you could wind up laying it over before you have a chance to do anything.and if people train their way to a better result.
