In a tunnel, you ride a motorcycle behind another vehicle without intending to overtake it. What regulatory minimum separation must you maintain?

Correct answer

At least 100 metres or a minimum four-second interval.

At least 100 metres or a minimum four-second interval. It is not calculated as twice the preceding vehicle’s length, and there is no 150-metre maximum. Also keep sufficient distance to stop without collision if the vehicle ahead brakes sharply, increasing it when conditions require. The 150-metre or six-second rule applies to vehicles with a maximum authorised mass above 3,500 kg.
