It’s one thing to drive a mobility scooter down to the supermarket, but it’s an entirely different one if you take it out on a dual carriageway.

While this isn’t exactly illegal in the U.K., police recommend against it. As Wales Online notes in light of the most recent incident that also went viral, police advise against riding mobility scooter’s down dual carriageways that have a speed limit over 50 mph.

This means that, if you do it, expect to become a part of the world’s slowest chase, because police will pursue you until you have safely left the road in question. As happened earlier this week, on the A470 at Merthyr Tydfil.

The video of the incident below, with Viral Hog saying that the person who shot it found the scene too hilarious to pass on the chance of immortalising it for eternity. After all, it’s not that often that you get to see a police car slowly pursuing a scooter.

South Wales Police told Wales Online that, though apparently hilarious, an incident of this type has the potential to become dangerous. On this particular occasion, they received several calls about the mobility scooter driving down the A470, so they decided it was best if they made sure the driver exited the road as quickly and as safely as possible.

“Officers located the scooter and its driver on the northbound carriageway between Abercynon and Pentrebach,” a spokesperson for the police says. “The man was escorted along the carriageway by a police vehicle to the Pentrebach exit in order to ensure his safety and that of other motorists.”

Because a mobility scooter reaches speeds of only 8 mph, police recommend you “avoid using dual carriageways with a speed limit of over 50mph.”
