when I first came to work in North Dakota on the Bakken every 5th vehicle was a car, the rest were all trucks.
there is still a huge amount of trucks on the road but it definitely has slowed down.
not that you cannot find a job driving trucks because you can.
as part of the requirement to draw unemployment insurance you have to make 4 job contacts a week.
if you are a truck driver and you apply with 4 companies for a truck driving job, all 4 will call you
