UK driving licences were introduced by the Motor Car Act 1903 but no test was required. The intention was purely to identify vehicles and their drivers. [9] The Road Traffic Act 1930 introduced age restrictions and a test for disabled drivers; this was the first formal driving test in the UK.
Braking distance refers to the distance a vehicle will travel from the point when its brakes are fully applied to when it comes to a complete stop. It is primarily affected by the original speed of the vehicle and the coefficient of friction between the tires and the road surface, [Note 1] and negligibly by the tires' rolling resistance and vehicle's air drag.
For heavy duty commercial vehicles it is recommended 4-6 seconds following distance for speeds under 30 mi/h (48 km/h), and 6-8 seconds following distance for speeds over 30 mi/h (48 km/h). [9] Rear-end collisions are the number one type of traffic collisions .
The rule is not a guide to safe stopping distance, it is more a guide to reaction times. The two-second rule tells a defensive driver the minimum distance needed to reduce the risk of collision under ideal driving conditions. The allotted two-seconds is a safety buffer, to allow the following driver time to respond.
d MT = braking distance, m (ft) V = design speed, km/h (mph) a = deceleration rate, m/s 2 (ft/s 2) Actual braking distances are affected by the vehicle type and condition, the incline of the road, the available traction, and numerous other factors. A deceleration rate of 3.4 m/s 2 (11.2 ft/s 2) is used to determine stopping sight distance. [6]
Loss of stopping power, or fade, can be caused by friction fade, mechanical fade, or fluid fade. Brake fade can be significantly reduced by appropriate equipment and materials design and selection, as well as good cooling. Brake fade occurs most often during high performance driving or when going down a long, steep hill.
Drivers in London had evolved a system for signalling their intentions to turn right or stop, using their arm, and this was seen to be of such benefit that it should be required and standardised as a code of behaviour across the country. The code allowed the driver to use either his own arm or a dummy arm – which had obvious benefits in wet ...
Driving in the United Kingdom is governed by various legal powers and in some cases is subject to the passing of a driving test. The government produces a Highway Code that details the requirements for all road users, including drivers. Unlike most other countries in the world, UK traffic drives on the left.
