You stop your car on a one-way street to unload some heavy boxes. Before you or your passenger step out and carry the boxes across the road, what should you do?

Explanation

The Highway Code Rule 11 states that on one-way streets you must check which way the traffic is moving and not cross until it is safe to do so. It also warns that bus and cycle lanes may operate in the opposite direction to the rest of the traffic. When loading or unloading a vehicle, you and your passengers may need to cross the road, so you must look carefully in both directions and check for traffic in any bus or cycle lanes before stepping out.
