You are driving a combination vehicle with a maximum authorised combination mass of 24 t. What is the longest time before you must interrupt your driving time for a break?

You answered correctly. For drivers of combination vehicles such as trucks and trailers with a maximum authorised mass over 3.5 tons, EU driving time regulations apply. You are allowed to drive for a maximum of 4.5 hours without a break. After this period, you must take a break of at least 45 minutes before continuing. This rule is designed to prevent driver fatigue and improve road safety. Remember: after each maximum driving period of 4.5 hours, a break is mandatory.
