Philadelphia Drivers License Practice Test

At a four-way stop, the vehicle that arrives first has the right-of-way. This rule is established to ensure a smooth flow of traffic and to minimize potential collisions at intersections where there are no traffic signals. When multiple vehicles approach the stop simultaneously, the practice dictates that vehicles on the right have priority, but the primary rule remains that the earliest arriving vehicle goes first. The other options do not govern the right-of-way effectively in this scenario. The size of the vehicle, whether it signals first, or the direction it is traveling (assuming it is straight versus turning) does not override the fundamental rule that prioritizes the order of arrival. This system is vital for maintaining order and safety at intersections, as it allows drivers to anticipate each other's actions based on established traffic laws.
