Fire lane marking signs are important traffic control devices used to identify and delineate areas designated for emergency vehicle access. These signs are typically painted on roads or displayed on posts, and are marked with specific symbols and colors to alert drivers to the importance of keeping these lanes clear at all times. Fire lane marking signs include symbols like a red circle with a white cross inside, red and white striped areas, and the words 'Fire Lane' or 'No Parking in Fire Lane' in bold letters. Violating these signs can lead to fines and legal penalties.
