Virginia Fire Programs EVOC Practice Test

Virginia Code 46.2-1040 governs the use of warning and signaling devices on emergency vehicles, specifically hazard lights and four-way flashers. This provision focuses on when and how those visual warning signals can be used to alert other drivers and keep scenes safe, such as when an emergency vehicle is stopped or assisting at a scene. The other topics—sirens or exhaust whistles (audible warnings), parking restrictions near fire hydrants, or impersonating emergency personnel—are covered by different laws, not this section. So this rule is the one that directly addresses hazard lights and four-way flashers on emergency vehicles, which is why it’s the best answer.
