What is the maximum number of hours you are allowed to spend at the wheel of a truck and trailer with a total permissible mass of 24 t within 2 weeks?

According to EU driving regulations, for drivers of trucks or buses, the maximum driving time allowed is 56 hours per week and 90 hours within two consecutive weeks. This rule is designed to ensure road safety by preventing over-fatigue among professional drivers. So, when driving a truck and trailer with a total permissible mass of 24 tons, you must not exceed 90 hours at the wheel within any two-week period. This includes all commercial trucking operations and is monitored through tachographs. Your answer is correct, and remembering the 90-hour rule is important for both passing the theory test and safe, legal driving in real life.
