Is 70mph the Perfect Speed Limit for Motorways in the UK? Should it Be Changed?

The current 70mph speed limit on UK motorways is often seen as far too restrictive for many drivers. While some argue that pushing for a 90mph limit could lead to political resistance, others advocate for a variable speed limit ranging from unlimited to 20mph, depending on conditions. This article delves into the arguments for and against the current speed limit and proposes alternative solutions.

Current 70mph vs. Proposed Alternatives

Mark claims that the current 70mph limit is too low and that increasing it to a minimum of 90mph (or even higher) would be a reasonable adjustment in today's climate. His rationale is based on the efficiency of modern internal combustion engines and improved braking systems, which support higher speeds safely. However, the politics make it challenging to implement such changes. There is also a concern that lowering the limit to 60mph might be a more palatable alternative for politicians to consider.

Variable Speed Limits for Optimal Driving Conditions

A variable speed limit that ranges from unlimited to 20mph depending on road and weather conditions would be more practical. On clear, dry roads with good visibility, there is no need for any maximum speed limit. Conversely, in adverse weather conditions, such as fog or icy roads, a lower limit of 20mph might be more appropriate. This dynamic approach would ensure that drivers can maintain the safest and most efficient speeds.

Mark points out that, in his personal experience, a 70mph speed limit seems inadequate, with 80mph being a reasonable alternative. He suggests that with modern vehicles and improved safety features, these higher speeds are justifiable. The days when a 70mph limit was sufficient have passed, given the advancements in car technology and driver safety.

Impact on Safety and Emissions

While Mark acknowledges that increasing speed limits rarely, if ever, improves safety for all road users, the impact on safety and emissions could be significant with variable speed limits. Reducing the national limit to 60mph could lead to safer driving conditions, as drivers would have more time and distance to react to unforeseen events. Moreover, it would result in reduced fuel costs and emissions, as vehicles operate more efficiently at lower speeds.

Conclusion and Future Considerations

To test the effectiveness of a lower speed limit, Mark suggests a trial basis. Implementing a 60mph limit for a trial period could provide valuable insights into its impact on safety, traffic flow, and overall road conditions. This approach would allow policymakers to gather data and make informed decisions regarding potential changes to the speed limit.

Ultimately, the ideal speed limit for UK motorways depends on a variety of factors, including road conditions, weather, and the needs of various road users. A more flexible and adaptive system could pave the way for safer and more efficient driving on UK motorways.
