As in North America, Belgian traffic travels on the right and passes on the left. If the space between a streetcar and the curb on the right is too narrow, streetcars may be passed on the left, providing oncom- ing traffic is not endangered. You can also pass a tram on the left on a one-way street. Within city limits, buses pulling into traffic from a marked bus stop have the right of way. Bus drivers will signal their intention to enter the flow of traffic with the use of directional signals.
Emergency vehicles have special right of way privileges.
Police cars, ambulances and fire trucks are identifiable by their flashing blue lights and multiple-tone warning sirens. Ordinary road users must immediately move to the side and give way, and stop if necessary. On autoroutes, the far right hand emergency lane must be left clear for emergency vehicles to pass. Funerals and other processions have right of way over all other traffic once the procession has entered the intersection. It is also illegal to cut into a group of children accompanied by a leader, a military convoy, or a group of cyclists taking part in a race.
