Motorcade

The term motorcade was coined by Lyle Abbot (in 1912 or 1913 when he was automobile editor of the Arizona Republican), and is formed after cavalcade, playing off of the last syllable in that word.

Eric Partridge called the name a "monstrosity", and Lancelot Hogben considered the word to be a "counterfeit coinage".

[5] A large, organised, group of vehicles will travel a busy route at very slow speed in order to deliberately cause traffic disruption.

Such a procession consists of several vehicles, usually accompanied by law enforcement support and additional protection to ensure the safety of the people in the motorcade.

The motorcade contains several armored vehicles, a USSS Electronic Countermeasures Suburban, a counter-assault team, and Secret Service agents.

These cars and motorcycles always drive ahead to clear the way and block traffic and also are in constant communication with the Secret Service.

[11] It includes two limousines heavily guarded by local law enforcement and Secret Service, with all cars driven by professional drivers.

[11] Motorcade routes are coordinated and selected by Secret Service agents in cooperation with local police forces or US military in war-torn countries.
