Malaga city council has said that Uber, Cabify and other private-hire firms will not have special passenger loading and unloading bays within the security cordons during this year's feria.
The move aims to prevent a repeat of last year's incident when private-hire cars were spotted by taxi drivers using public transport lanes without permission. This sparked a lightning strike by taxis that caused massive disruption along the Costa del Sol for several days.
This time the council is taking no chances and private-hire vehicles will face the same access restrictions as any normal car.
Taxis are unhappy at what they claim is unfair competition from app-based start-ups like Uber, which is operating on the Costa during Malaga fair for the first time.
Uber had launched an advertising campaign in the city saying "See you at the feria".
