Final answer:
In a funeral procession, all vehicles must follow the lead vehicle and can disregard stop signs and traffic control signals once the procession has started moving through an intersection. This rule applies as long as the vehicles are properly marked and the first vehicle has obeyed the initial signs or signals. Variances in local laws must be considered.
Step-by-step explanation:
The question relates to traffic laws concerning funeral processions. Generally, special rules apply to funeral processions to ensure they can stay together and that the procession is treated with respect. In most jurisdictions, once a funeral procession has started through an intersection, typically led by a police escort or a vehicle with a flag indicating it's a funeral procession, all vehicles in the procession are usually allowed to follow through the intersection without stopping, even if there is a stop sign or traffic control signal. It is important to check local laws and regulations as they can vary from place to place.
Therefore, the correct answer is 4) All vehicles in the funeral procession must follow the lead vehicle and disregard stop signs and traffic control signals, unless otherwise directed by a traffic officer. That being said, before entering an intersection, the first vehicle in the procession must obey traffic lights and stop signs. Once it proceeds, the following vehicles can continue through stop signs and signals as long as they display the standard funeral procession markings.
For the safety of all, other drivers who are not part of the procession are expected to stop moving and become stationary till it passes by and should not run toward or run alongside the procession.
