CDL Class B to Class A Upgrade ELDT Certificate
The CDL Class B to A Upgrade ELDT certification is a training program designed to prepare a holder of a Class B commercial driver's license (CDL) to upgrade to a Class A CDL. This certification is required for Class B CDL holders who want to operate Class A vehicles, which are combination vehicles: semi-trucks and tractor-trailers.
To be eligible to upgrade to a Class A CDL, an individual must already hold a valid Class B CDL.
Even though they already hold CDLs, Class B CDL holders must first obtain a Commercial Learner's Permit (CLP) to practice driving Class A vehicles.
Class B CDL holders must pass a series of written and driving tests to demonstrate their knowledge and skills for driving Class A vehicles.
Class B CDL holders must become qualified to operate vehicles with air brakes if they have not already done so.
CDL B to A upgrade key points
CDL Class A ELDT certification is typically required for operating semi-trucks and tractor-trailers.
CDL Class A vehicles are typically larger and more complex to operate than Class B vehicles. However, much of the basic knowledge of Class B vehicles is applicable to driving Class A vehicles as well.
Class B holders are still required to demonstrate a high level of knowledge and skill to operate the special features of Class A vehicles safely. Air brakes qualification is a must.
Individuals seeking Class A CDLs are required to pass a more rigorous set of written and driving tests than those with Class B or Class C licenses. This is because operating Class A vehicles requires a higher level of skill and knowledge. Knowledge of air brakes is a must.
CDL Class A holders are often paid more than those with lower-class licenses because they can operate a wider range of vehicles and typically have more responsibilities.
CDL Class A holders must obtain additional endorsements to operate certain types of vehicles, such as tankers or double- or triple-trailer combinations.
CDL Class A holders are often subject to random drug and alcohol testing to ensure that they are not impaired while operating a commercial vehicle.
A Class A CDL is required to legally operate a "trailer bus": a semi-truck in which the semi-trailer is outfitted to carry passengers. However, such vehicles are extremely rare on America's roads.
