All roads maintained by Camden Council have a 20 mph speed limit. A borough-wide speed limit using signage only was introduced in December 2013. Many streets in the borough were already part of a 20 mph zone, with traffic calming, which has remained in place. The Council regularly monitors the speed of traffic; only the Metropolitan Police are able to enforce the speed limit.
The Transport for London Road Network (TLRN) ‘red routes’, which are managed by
TfL, are not included in the borough-wide 20 mph limit and generally have a 30 mph
speed limit. Some red routes (Camden High Street, part of Camden Street, part of King’s
Cross Road and Farringdon Road) have 20 mph limits and additional red routes may become
20 mph over time.
