Which of the following actions is illegal when driving in Florida?

Driving with a revoked license is illegal in Florida. A revoked license means that the driver's privilege to operate a vehicle has been terminated by the state due to various reasons, such as severe traffic violations, DUI offenses, or failure to pay fines. Operating a motor vehicle without a valid license puts the driver at risk of fines, legal penalties, and even incarceration. Consequently, it's essential for drivers to ensure that their licensing status is valid before getting behind the wheel.

In contrast, stopping at a red light, using turn signals, and parking in designated spots are all legal and required actions that contribute to safe driving practices and orderly traffic flow. Following traffic signals is fundamental to preventing accidents, while using turn signals is necessary for informing other drivers of one’s intentions. Parking in designated spots ensures that vehicles are parked appropriately and do not obstruct traffic, which is crucial for maintaining road safety and accessibility.
