A man has been charged with assault after a meth-fuelled road rage incident and crash in which both drivers tested positive for the drug.

Two police vehicles travelling on Brand Highway around 4.30pm on Tuesday stopped when a man was seen punching another driver near the traffic lights at Ackland Road in Mt Tarcoola.

A vehicle had crashed into the back of another at the lights. One of the drivers has been charged with assault as a result of the alleged attack.

Police say drug tests performed at the scene and at the Geraldton station found both drivers were under the influence of methamphetamine.
