The rate for mileage and for gas are completely different and is dependent upon the company in which you work. Gas is considered an expense and as such receipts for gas should be submitted to your company and you should be reimbursed for the actual amount of gas purchased if they don't pay mileage. Mileage includes everything from gas to wear and tear on your vehicle and the insurance you pay on your car. The current dollar rate per mile in the U.S. is 48 cents. That's also the amount you can claim on your taxes if you're not paid for gas or mileage by the company.
There isn't a set rate. It comes down to experience, the company they work for, the type of commodity being hauled, and the method which they're paid.. they may be paid by mileage, percentage, salary, or hourly, depending on the specifics of their job.
