Twenty thousand motorists were stopped in Quebec for using the wrong side of the road when riding a motorcycle.

Before the exclusive motorcycle lanes in Quezon City went into effect today, more than 20,000 drivers were stopped on Sunday, according to the Metropolitan Manila Development Authority (MMDA).

4,527 of the 20,656 violators were motorcycle riders who were caught straying from their designated lane, according to MMDA data.

16,129 of them, on the other hand, were operators of four-wheeled vehicles who had been harassed for using the lanes designated for motorcycles.

Drivers of other vehicles will now be subject to a P500 fine for infractions, while P1,200 will be levied against drivers of public utility vehicles (PUVs).

The motorcycle lane is situated on Commonwealth Avenue, which runs from Elliptical Road to Doa Carmen Street and is notorious for fatal car and pedestrian accidents.

Bikes have their own lane, PUVs have their own lane, motorcycles have their own lane, and all other motor vehicles have their own lane.

At 200 meters from the U-turn slot, drivers who want to make a U-turn may veer from their designated lane.

Vehicles may swerve from their lane using the transition lines or pavement markings at a minimum of 100 meters from their dedicated lane when entering or exiting side streets or intersections.

Following numerous violations during the dry run, the MMDA is working with the government of Quezon City to enforce adherence to the designated motorcycle lane.

The goal of the policy, according to the MMDA, is to lessen motorcycle-related traffic accidents while preserving a smooth flow of traffic.
