People often ask if they have to go back to truck driving school in order to get a trucking job with not recent experience. It depends on how long ago you were driving. Probably how long you drove for as well.
Having said that, the details of what you will experience will depend on the trucking company that you go to. Most companies want your experience to be within the same year. Once you have been off the road for more than a year, only a few trucking companies will take you on.
With less experience more than an year old but less than 2, there are
a few companies that will hire but most will want you to at least
attend a refresher course. Some trucking schools and companies have
refresher courses which are cheaper and shorter than most schools.
