Problems with traffic lights need to be reported to your local council. It's only a police issue if it is a major A road and a traffic light problem could cause an accident.
Road defects should be reported directly to your local council unless the damage has just happened and is causing traffic problems, or it is so large that cars are having to take evasive action. If this is the case then please call 101.
Debris in a live carriageway should be reported to us on 999 or 101.
999 is appropriate if it is a motorway or major road and cars are swerving to avoid it, causing a danger to other road users.
101 is appropriate for slower residential roads where evasive action is not as likely to cause further problems.
