What does the traffic sign with a car and a limit signify?

The traffic sign depicting a car along with a numerical limit specifically indicates the maximum speed permissible for vehicles traveling on that road, usually expressed in kilometers per hour (km/h). This type of sign serves as a crucial guideline for drivers to maintain safe speeds and follow legal speed regulations, thereby enhancing road safety for all users.

In many jurisdictions, including Italy, adherence to posted speed limits is legally mandatory, and violations can result in fines or other penalties. Recognizing this sign and understanding its implications is essential for effective driving, as it helps prevent accidents caused by speeding or reckless driving.
