# You are travelling on a smart motorway and the hard shoulder has a red cross above. All other lanes are showing a mandatory speed limit. What does this mean?

DVSA-style practice question · Motorway Rules

## The answer options

-   The hard shoulder has a 50mph limit 
-   The hard shoulder can be used as normal 
-   The hard shoulder can be used to rest 
-   The hard shoulder is for emergency use only**Correct** 

## Why that is the answer

A red X displayed above any lane, including the hard shoulder, indicates that the lane is closed to traffic. Driving in a closed lane is illegal and dangerous. When a red X is shown over the hard shoulder on a smart motorway, it must only be used in an emergency or breakdown. The Highway Code strictly forbids using the hard shoulder for resting or as a normal running lane when it is closed.

## How this comes up in the real test

Questions from motorway rules appear throughout the 50-question multiple-choice section, and the wording changes between versions. Learn the rule rather than the sentence: the DVSA can ask the same point from the opposite direction, and a memorised answer falls over the moment the phrasing moves.

The pass mark is 43 out of 50, so seven wrong answers is your entire margin. If a whole category is shaky, run the topic practice below until you are getting every question right for the right reason, then go back to full mocks under the clock.

## Passed your theory? Get the practical booked

Your theory certificate lasts two years. Most learners who use it quickly do it with an intensive course — a block of hours with a DVSA approved instructor and a practical test at the end, instead of one lesson a week for months.
