There is the fact where 70% of the transported good in the US are transported by trucks. That is more than enough percentage to make you consider and get involved in the OTR trucking.
Conclusion
If we compare the over the road trucking (also known as OTR or long haul trucking) with the local trucking jobs I must mention the required period of time that you need to be away from home.
With local trucking jobs you get up in the morning do your job and get back in the evening. The OTR trucking does not give you the convenience of your home. That is why many of the new OTR drivers after 2 or 3 rounds living this lifestyle are quitting this job.
But if you can deal with the loneliness ORT trucking is the right job for you. It brings more money in the end. Grab the opportunity and spread your wings because the highway is your sky.
