Leaving the air conditioning on in your parked car could cost you more than you think. Recent updates have increased the fines for this offense, even though the rule itself is not new.
What the Law Says
This regulation isn’t a recent introduction—it dates back to 2007. What’s new are the updated penalty amounts. The law prohibiting the use of air conditioning in parked vehicles is outlined in Article 157 of the Highway Code, specifically paragraph 7-bis, which states:
“It is prohibited to keep the engine running while the vehicle is parked for the purpose of operating the vehicle’s air conditioning system. Violations result in an administrative fine ranging from $223.00 to $518.00.”
Why the Law Exists
The main goal of this law is to reduce pollution. While driving, the engine must naturally remain on, and using the air conditioning is fully allowed. However, when the vehicle is stationary and parked, keeping the engine running—just to power the air conditioning—leads to unnecessary emissions, especially from older, combustion-engine vehicles.
These engines emit significant amounts of CO₂, contributing to air pollution and climate change. As a result, drivers are required to turn off the engine when the vehicle is not in motion.
Why It’s Back in the Spotlight
This issue has resurfaced due to recent record-breaking heat waves, with temperatures exceeding 40°C (104°F) in several cities. The Ministry of Health has issued red alerts for extreme heat in locations such as:
Ancona
Bologna
Bolzano
Brescia
Cagliari
Campobasso
Rome
In these scorching conditions, it might be tempting to sit in a parked car with the A/C on—but doing so could get you fined by traffic police.
