# Road narrows on both sides — UK road sign

This sign warns that the width of the road decreases symmetrically ahead from both directions.

The road narrows on both sides sign features a red warning triangle containing two inward-sloping parallel black lines.

It alerts drivers that usable carriageway space decreases ahead, which may create passing difficulties or require merging.

## What this sign means

The sign warns that the road ahead narrows equally from both the left and right sides.

- Red warning triangle border
- Two symmetrical lines bending inward
- Indicates reduced carriageway width ahead

## What to do when you see it

Check your mirrors and adjust your speed. Keep central within your lane and be prepared to yield space to wide or oncoming vehicles.

- Slow down to assess road clearance
- Avoid overtaking near narrowed sections
- Watch for cyclists who need extra safe clearance

## How this sign is tested

DVSA theory tests evaluate your hazard recognition skills regarding spatial margins and priority rules at narrow chicanes or bridges.

## Common mistakes

Maintaining high speed into narrowed sections, risking wing-mirror damage or forcing oncoming traffic to brake sharply.

## Test yourself on this one

Road and traffic signs is the biggest category in the question bank with 102 questions, and signs turn up inside other categories too. Work through them free, no sign-up needed.

## Frequently asked questions

Does this sign give priority to either side?

No, this warning sign simply alerts drivers to road width reductions without establishing right of way.

Where is this sign commonly located?

It is frequently positioned ahead of narrow bridges, traffic calming chicanes, or roadwork zones.

Should I pass cyclists before the narrowing section?

Only if you can give at least 1.5 metres clearance; otherwise wait behind until the road widens.

## 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.
