Allowed actions for 670V50

Adjust speed before the sign takes effect.Keep a safe following distance for the speed and conditions.Use lower speeds where visibility, weather, traffic, or road surface requires it.Watch for repeaters, zone endings, and signs that change the applicable limit.

Do not exceed a signed maximum speed limit.Do not drive below a signed minimum speed without a valid safety reason.Do not accelerate before the restriction has ended.Do not treat the posted number as safe when conditions require a lower speed.

670V50 - Maximum speed 50 mph (80 km/h) road sign FAQ

Get clear, practical answers to the most common questions about the 670V50 - Maximum speed 50 mph (80 km/h) road sign. Learn how the sign works, what rules it represents, and how it affects real driving situations. This FAQ strengthens your understanding and supports accurate decision making for the British driving theory exam in Great Britain.

What does the 670V50 maximum speed 50 mph sign mean?

The 670V50 sign, displaying '50' within a red circle, legally prohibits you from driving faster than 50 mph (80 km/h). It is a maximum speed limit, not a target speed.

Do I have to drive at exactly 50 mph when I see this sign?

No, you must not exceed 50 mph. The sign sets the upper limit. You must always drive at a speed appropriate for the conditions, which may be significantly lower than 50 mph due to rain, fog, heavy traffic, or poor road surfaces.

Where are 50 mph speed limit signs typically found in Great Britain?

These signs are often used to reduce speed limits on certain stretches of road where conditions warrant a lower maximum speed, such as areas with increased traffic, narrower roads, or greater accident potential, outside of built-up areas where national limits might apply.

What are common mistakes learners make with speed limit signs like 670V50?

A common mistake is treating the posted speed limit as a target speed, driving at 50 mph regardless of conditions. Another error is accelerating as soon as the sign is passed, without checking if the limit has ended or if conditions require a slower speed. Always anticipate and react safely.

What should I do before I reach a 50 mph speed limit sign?

You should anticipate the sign and begin to slow down progressively before you reach the point where the speed limit starts. This ensures you are at or below the legal speed limit when you pass the sign and are not braking sharply or accelerating suddenly.

Are there signs that indicate the end of a 50 mph speed limit?

Yes, speed limits are usually indicated by a sign showing a diagonal bar across the speed limit number (e.g., 50 with a diagonal bar), or by another speed limit sign indicating a different speed. It's important to watch out for these 'terminal signs' or repeaters that change the applicable limit.
