Most Motorists Are Unsure About This Common Road Sign – Here’s What It Means
Do You Know What This Road Sign Means? Most Drivers Don’t!
If you’ve driven on UK roads, you’ve likely seen this mysterious road sign—a white circle with a single black diagonal stripe. However, one driver sparked debate online by claiming that 99% of motorists don’t actually know what it means.
A Reddit user posted a photo of the sign with the caption:
“I’m convinced 99% of drivers don’t know what this sign means.”
So, what does this often-misunderstood sign actually indicate?
The Meaning of the Black and White Road Sign
According to the RAC (Royal Automobile Club), this sign represents the National Speed Limit (NSL) for the next stretch of road. This means that any previous speed restrictions—such as those imposed by roadworks or temporary limits—no longer apply.
But here’s the catch: the national speed limit varies depending on the type of road you are driving on.
What is the National Speed Limit in the UK?
- Motorways & Dual Carriageways: 70 mph
- Single Carriageway Roads: 60 mph
- Built-up Areas (if no other signs are present): 30 mph
Drivers should remember that these limits only apply in ideal driving conditions. Bad weather, heavy traffic, or hazardous road conditions may require you to drive at a safer, lower speed.
Why This Road Sign is So Important
Many motorists mistakenly believe this sign means they can drive at any speed they want, but that’s not true. The sign is in place to maintain road safety and ensure a steady flow of traffic.
✔ It reminds drivers to adjust their speed based on road type and conditions. ✔ It removes outdated or temporary speed limits, restoring normal speed regulations. ✔ It helps prevent unnecessary speeding tickets for drivers who understand its meaning.
Common Misconceptions About the National Speed Limit Sign
❌ “It means I can drive as fast as I want.”
- No! The sign indicates that the national speed limit applies, but you must always drive safely and within legal speed limits.
❌ “It means the speed limit is 70 mph everywhere.”
- Not true! The speed depends on the type of road you are on. It’s 60 mph for single carriageways and 70 mph for motorways and dual carriageways.
❌ “I don’t have to follow the flow of traffic.”
- Wrong! Even if the national speed limit applies, you should adjust your speed based on traffic flow, visibility, and road conditions.
Why Every Motorist Should Recognize This Sign
Knowing and understanding road signs is essential for safe driving. If a large percentage of drivers don’t recognize or misunderstand this sign, it could lead to dangerous situations, including:
🚨 Sudden braking when drivers realize they misjudged the speed limit. 🚨 Increased risk of speeding fines for those who don’t realize they’ve entered a national speed limit zone. 🚨 Unsafe driving conditions when some motorists speed up dramatically while others stay cautious.
By recognizing this sign, drivers can make better decisions, improve road safety, and avoid unnecessary penalties.
