Most learners know what double yellow lines mean, but what about double and single red ones? An increasing number of ‘red routes’ are appearing across the UK, especially in big cities and around busy places such as airports and hospitals to act as a strong deterrent to stopping, even for a second or two. Essentially, they’re a very strict version of double yellow lines and tend to be more heavily enforced with fines if you stop on them. Red routes were first introduced in London during 1991 to form urban clearways and ease traffic hot spots. They now cover five per cent of the Capital and are increasingly popular with local authorities nationwide. Double red lines marked along the left of your inside lane indicate that no stopping, waiting or parking is permitted by any vehicles at any time. A single red line tells you that no vehicle is allowed to stop during the hours of the route’s operation which is clearly displayed on roadside signage. Both double and single red lines mean you can’t drop off or pick up passengers or load or unload goods and apply equally to cars, vans and lorries. The only way you can stop on a red line is if you’re held in traffic or at a red light. Red routes also prohibit U-turns, and in some cases, there may be lane restrictions to watch out for.
