What should you do if you mistakenly pass the exit you intended to take on a multi-lane carriageway?

If you mistakenly pass the exit you intended to take on a multi-lane carriageway, the safest and most appropriate action is to continue to the next exit. This approach is crucial for maintaining safety on the road, as making sudden maneuvers can lead to accidents or disrupt the flow of traffic. By proceeding to the next exit, you can then safely navigate back towards your intended route without jeopardizing your safety or that of other road users.

The other actions, such as making a U-turn at the next junction or attempting to reverse, can create dangerous situations and are often illegal on multi-lane carriageways. Using the hard shoulder to turn around is also highly discouraged, as it is designated for emergencies only and is not a safe maneuver in typical driving situations. Therefore, continuing to the next exit is the most logical and safe solution in this scenario.
