Varies by what you drive, who you drive for, specifics of your job, and level of experience you possess.
As much as the company decides to pay them.
As much as their company pays them. There isn't a set rate, and it depends on a lot of things, including where they live, and the exact nature of their job. Not all CDL jobs are equal, and not all CDL jobs are limited solely to driving a truck.
Depends on what exactly their job is. Not all CDL jobs are equal.
No. In fact, it's more likely to increase. With a CDL, you're in a much higher risk category for being in an accident, on account of how much more time a CDL driver spends on the road than a daily driver.
As much as the company sees fit to pay them. There isn't a set rate for this, and the pay rate will be determined by the area of hire, the driver's experience, and other factors.
You will fail a CDL drug test with ANY detectable amount of THC in your system.
It will vary depending on the specifics of the job, the company, and how much experience the driver has. Not all Class 1/2/3/etc. jobs (Canada does not have the CDL) are going to be the same.
Depends on which Class of CDL. A driver with a Class C CDL is not licensed on that vehicle. A driver with a Class B CDL can drive that combination only if the GVW of the trailer is less than 10,000 lbs. A driver with a Class A CDL can drive it.
There isn't a set rate. There are three classes of CDL, and hundreds of jobs which require a CDL (not all CDL drivers do nothing but drive a truck). Where they live and what exactly they do will affect what they're paid.
Depends on the job, the company, and how much experience the employee has. There are a wide variety of jobs involving a CDL, and a wide range of pay scales accordingly.
Sure you can - but not as a CDL driver.
You can drive vehicles which require the operator to possess a CDL....
