Driving a Commercial Motor Vehicle (CMV) requires a higher level of knowledge, experience, skills, and physical abilities than that required to drive a non-commercial vehicle. In order to obtain a Commercial Driver's License (CDL), an applicant must pass both skills and knowledge testing geared to these higher standards. Additionally CDL holders are held to a higher standard when operating any type of motor vehicle on public roads. Serious traffic violations committed by a CDL holder can affect their ability to maintain their CDL certification. Driving a commercial motor vehicle is a big responsibility. It requires special skills and knowledge. Most drivers must obtain a commercial driver's license (CDL) through their home State (it is illegal to have a license from more than one State). In addition, special endorsements may be required if you or your company drivers will be driving any of the following vehicles: a truck with double or triple trailers a truck with a tank a truck carrying hazardous materials a passenger vehicle • Payment will be made to iTunes account by way of confirmation of purchase. • Subscriptions are automatically renewed unless automatic renewal is turned off at least 24 hours before the end of the current period. • The account will be charged for renewal within 24 hours before the end of the current period, and the renewal fee will be determined. • The subscription can be managed by the user, and the user can turn off automatic renewal through the user's account settings after purchase.
