What is the proper breakdown procedure on a single and dual carriageway?

The proper breakdown procedure on a single and dual carriageway involves ensuring safety for both the vehicle occupants and other road users. Stopping and pulling over onto the hard shoulder is vital, as this minimizes the risk of collision with passing vehicles. Getting behind the barrier, if available, provides an additional layer of safety by creating distance from the moving traffic.

This procedure is particularly important on busy roads where high speeds increase the danger of accidents. Remaining in the vehicle is generally advised only in situations where escape is not possible, and visibility may already be compromised by traffic. Therefore, pulling over to a secure location like the hard shoulder and then positioning oneself behind a barrier significantly enhances safety during a breakdown.

The other options do not encompass the full safety measures recommended for such situations; for instance, staying inside the vehicle without moving to a safer location exposes occupants to unnecessary risks. Using a warning triangle without proper positioning on the hard shoulder also fails to address safety adequately.
