When people drive a car, they generally follow speed limits. This is applicable for any country, not just the United Kingdom. These road speed limits are used to limit the maximum legal speed for motor vehicles on any of the UKs motorways. Each speed limit sign is placed near street lighting to ensure visibility even in the night. The speed limit for different types of roads may be clearly defined by the following:
i) 70 mph (112 kmph) on motorways
ii) 70mph (112 kmph) on dual carriageways
iii) 60mph (96kmph) on single carriageways
iv) Generally, 30mph (48kmph) on restricted roads
These limits are applicable to all the different types of vehicles on the road such as: cars, motorcycles, delivery vans, etc. For example, on a certain road, a car may have a speed limit of 50mph, whereas a goods vehicle may be limited to 40 mph since its weight will be more, and the impact on the road will be more at higher speeds. If you break these, you may need speeding solicitors to become involved.
Enforcement of these speed limits on UK motorways is generally done through police “speed traps”, speed guns, automated in-vehicle systems, and automated roadside traffic cameras. Some of the reasons as to why these were set up are due to a need to define maximum traffic speeds to reduce road accidents, to reduce negative traffic impact, to increase fuel efficiency and finally to satisfy the locality wishes.
Some roads have variable speed limits, which vary according to weather, traffic levels, the time of day, or for any other reason such as road accidents ahead, etc. In some rare cases, related to speeding solicitors, where there may even be a minimum speed limit, for example in the “Mersey Tunnels”, to facilitate safe passage through hazardous or enclosed areas.
The government justifies speed limits along the lines that they are used to appropriate traffic speeds for safety purposes, as well as environmental and accessibility reasons. The safety aspect for traffic speed limitation was introduced in the 1930s, as the number of road related casualties was on the rise. In terms of environmental reasons, when a vehicle travels at a constant speed, the fuel consumed is less as well as the emissions when compared to a vehicle travelling at constantly varying speeds.
A regulation on the speed a vehicle is travelling with is advantageous as well to the other road users, such as pedestrians, cyclists, and slower moving vehicles. In most cases, a red circle with the speed limit in it is used to define the maximum speed limit for that road. Either the limit is in mph or kmph depending on the locality. For defining the minimum speed limit, a blue circle with the limit within it is used.
Some vehicles may be retrofitted with speed limiters. For example, some heavy vehicles such as buses or goods vehicles (lorries) may have speed limiters which restrict the fuel intake of the engine, thereby preventing it from reaching its maximum speed. All in all, we can conclude that speed limits on UK motorways are an extremely essential to prevent road accidents, and to reduce environmental constraints brought by over-speeding cars’ emissions, so be careful to follow these or speeding solicitors may become involved.
