This is really up to you. First training sessions in the Heavy Rigid trucks are recommended to be one hour, as the first training session is often quite exhausting. Subsequent training can be booked for two hours. Heavy Combination and Multi Combination training are usually booked for two hours or longer as these are usually undertaken by experienced drivers who already have a truck licence. The smaller Light and Medium Rigid Trucks are often booked in a three to four hour block including your assessment at the end of it.
