What is the reason for the 3-meter parking rule near fire hydrants?

The 3-meter parking rule near fire hydrants is primarily in place to ensure that fire trucks can access hydrants quickly and efficiently in case of an emergency. Firefighters rely on these hydrants to supply water for firefighting efforts, and any obstruction can delay their response time. By maintaining clear space around hydrants, it prevents vehicles from blocking access, allowing emergency services to operate without hindrances. This is particularly crucial in urban areas where traffic congestion is common, and rapid response to emergencies can make a significant difference in saving property and lives.
