Smart motorways are useful for improving traffic flow, but it is important to be aware that it is now illegal to drive in a lane that has a red X sign overhead and this could result in three points on your license and a fine of up to £100 or more serious consequences in dangerous cases. It is clear that the government is doing all it can to encourage motorists to switch to electric cars and to hit clean air targets, so it is not a surprise that Clean Air Zones are being introduced to major cities including Birmingham, Bath, Oxford, Leeds and Bristol. Motorists also need to be aware of changes in driving in the EU as a result of Brexit.
