PSP warns truck drivers over use of fast lane on bridges; 26 cases prosecuted last year

The Public Security Police Force (PSP) has issued a warning to heavy-duty vehicles, including trucks and buses, against driving in the right-side traffic lane (fast lane) of local bridges.

In the notice, the PSP reminded drivers of such vehicles that they must remain “in the left lane at all times,” noting that “overtaking other vehicles” on the bridges is strictly prohibited to prevent traffic accidents.

The PSP noted that specific regulations enforced in Macau prohibit vehicles of this type from driving continuously or temporarily (while overtaking) in the right-hand lane of the Sai Van and Amizade Bridges, with violations subject to a fine of MOP6,000. At the same time, traffic signage prohibiting heavy vehicles from overtaking is posted along the Macau Bridge, and violations result in a fine of MOP600 under the Road Traffic Law.

According to PSP data, there were 26 prosecutions for heavy-vehicle overtaking on cross-sea bridges in 2025.

The force further explained that heavy vehicles have longer braking distances, and sudden lane changes can easily lead to traffic accidents, which often result in more severe consequences.

The same force noted that, under the same traffic regulations and specific bridge traffic rules, there are legal provisions addressing cases in which a heavy vehicle maneuvers to avoid an obstacle or a stopped vehicle (immobilized for reasons other than traffic congestion). In these cases, such maneuvers are not considered “overtaking.”

Still, the PSP notes that drivers should strictly comply with the rules, signal their intent to change lanes in advance, and return to the left lane as soon as possible.

The PSP noted that continued surveillance on sea-crossing bridges ensures that drivers strictly comply with the regulations and that safety remains a priority.

It is common practice in Macau for drivers (including light vehicles) to use the fast lane (right lane) when crossing bridges and to remain there throughout the crossing, even when the left lane is clear.

Despite this practice also being punishable by law and the bridges having signage urging drivers to keep left when possible, there are no records of the PSP targeting this practice. Such a practice also leads to another commonly seen violation in which vehicles overtake from the left side because the vehicle in front is driving more slowly in the right lane.

The PSP has not provided any statistical data on these cases at this time.
