A dedicated trucking job mean a more predictable schedule and could mean more time at home.
Dedicated trucking jobs come in many flavors just as all other driver opportunities. It could mean that you are running a dedicated account. This means you only serve a particular customer's stores. For instance Werner has dedicated Dollar General, J.B. Hunt has dedicated Target accounts.
It could also mean that you handle a certain customers withing those accounts.
Dedicated routes could serve a certain area, and companies in that area as needed, or it could be literally the same route each time a driver is out.
The dedicated route could be in a dedicated account or not.
These dedicated trucking jobs could be doing the exact same thing every week or alternate each week.
etc, etc, etc,
Dedicated trucking are perfect for some drivers. Those drivers that need to be home more often might find a trucking company with routes that go out and come back in 2 or more times a week or out all week and back in the weekend.
There are dedicated trucking jobs for experienced and new drivers. Availability will depend a lot on where you live. Remember the nature of the job is in (home base) and out (receiver or customers). When you think about it, generally speaking, that means the run will generate from a place where there are large manufactures or distribution centers getting product out to retail stores.
So if you live in an area that has a lot of large manufacturers or distribution centers your changes of finding a dedicated run and getting home of the regular is higher than someone who stays off the beaten trail.
Large trucking companies are not the only ones with dedicated driver opportunities. Small and medium sized trucking companies also offer these routes.
Dedicated runs can pay really well since the trucking company sometimes has an ongoing relationship the customers they serve. There is a higher level of commitment and expectations so rates can be higher and driver pay could be nice.
Of course this depend on the trucking company you are hired at. Just saying the opportunities are out there so do a little searching before committing to the first thing that you see, especially if you stay in a large city.
