Live Traffic Camera—A40(M) Paddington Slip

The A40(M) Paddington Slip area follows typical London traffic patterns — weekday rush hours (07:30–09:30 and 16:30–19:00) are consistently the busiest periods, with school term-time adding pressure around 08:15–09:00 and 15:00–16:00 on school days. Midweek tends to be heavier than Mondays or Fridays, when more people work from home. Saturday lunch and early afternoon can also be surprisingly busy for shopping and leisure trips. The live JamCam above, updated every five minutes by TfL, is the most reliable way to check actual conditions right now.
