Highway Code

In the UK, the national speed limit for cars on a single-carriageway road is 60 mph to manage safety on roads without physical central barriers. Option C is incorrect because 70 mph is the limit reserved for dual-carriageways and motorways, while Option A is too low for the default national limit.

Pelican crossings use a unique flashing amber light phase that allows drivers to proceed if the crossing is completely clear. Other crossings, like puffin crossings, use smart sensors and do not feature a flashing amber light, instead remaining red until pedestrians have finished crossing.

In the UK, the national speed limit for cars on a single-carriageway road is 60 mph to manage safety on roads without physical central barriers. A diagram for this topic isn't available yet — the worked example below walks the same reasoning step by step.

• !Option C is incorrect because 70 mph is the limit reserved for dual-carriageways and motorways, while Option A is too low for the default national limit.
• !It does not refer to mirror check frequency, making option A incorrect, as mirrors should be checked dynamically based on road conditions.
• !Other crossings, like puffin crossings, use smart sensors and do not feature a flashing amber light, instead remaining red until pedestrians have finished crossing.
• !Larger vehicles do not have automatic priority over smaller ones, though drivers should give them extra room to maneuver safely.
