Marshals are a group of volunteers wearing orange overalls and helping complete a race smoothly. There are different types of marshalls in F1 races and their role on the track varies.
Trackside marshalls, flag marshalls, pit marshalls, startline marshalls, paddock marshalls, and administrative marshalls are the types of marshals now. Marshalls usually don’t get paid and they must be passionate about F1.
Anyone can be a marshall in F1 races, as long as they are physically fit to do the job and an F1 enthusiast. There are clubs in the UK that people can join to become an F1 marshall.
