Cyclists are not allowed to drive on motorways but are free to cycle on both dual carriageways and A roads. However, there are important exceptions: Cyclists must not cycle on dual carriageways or A roads where there are signs prohibiting them (under a specific traffic regulation order) They must not cycle onto the part of an A road which has been designated a motorway While the general rule is that you can cycle on dual carriageways and A roads, you will appreciate that the risks are greater – particularly where the speed limit is 70mph. Even so, you still have priority as a cyclist, so if you’ve been involved in a collision it’s highly likely it was caused by a negligent or dangerous driver.
