A personal mobility device rider travelled along all three lanes of Upper Serangoon Road at more than 70km/h and overtaking all other motorists.

The footage was taken by a motorcyclist's helmet camera.

It appeared the motorcyclist had a hard time accelerating and keeping up with the PMD rider without a helmet on.

The PMD rider effectively overtook at least 30 other vehicles on the road in that 1.2km stretch, by weaving from right-most to left-most lane, and even avoiding road works by filtering to the merging lane without signalling.

When the motorcyclist had to turn right into Hougang Avenue 2, the PMD rider carried on with his journey along Upper Serangoon Road.

700 cases of PMD on roads and expressways

There has been 700 cases of riding personal mobility devices (PMDs) on roads and expressways in the first nine months of 2019, according to the Land Transport Authority (LTA).

This is despite a ban on riding personal mobility devices (PMDs) on roads and expressways.

The actual number of offenders could be even higher as many violations go undetected.

The Singapore government warned on Oct. 7 that it may have to completely ban PMDs if errant users' behaviour does not improve.

Under the Road Traffic Act, it is illegal for PMDs -- such as e-scooters and hoverboards -- to be used on roads from Jan. 15, 2018, with first-time offenders subject to a fine of up to S$2,000, a jail term of up to three months, or both.

PMDs can be used on only footpaths and shared paths.

Bicycles and power-assisted bicycles are allowed on roads.

PMD riders caught riding illegally on roads and expressways will have their devices immediately impounded.

The PMD riders will also be punished and all devices found with illegal weight, width or speed enhancements will be forfeited.

There are approximately 90,000 registered PMDs in Singapore.
