Sound Horn Sign CAD Block
The Sound Horn Sign CAD Block (ISO 7010 M029) is essential in environments where drivers or operators are required to sound their horn to alert others of their presence. This mandatory safety symbol helps prevent collisions and enhances communication in areas with limited visibility or high pedestrian activity.
This Mandatory sign CAD block displays a blue circular background with a white pictogram of a horn. Designed according to ISO 7010 and ISO 3864-1 standards, the symbol provides clear and internationally recognized guidance. Its bold, high-contrast design ensures excellent visibility even in noisy, industrial, or traffic-heavy environments.
You can easily incorporate this CAD block into AutoCAD or any major CAD drafting software. It is ideal for warehouses, construction sites, vehicle depots, and other areas where audible warnings are necessary for safety. Typical sign sizes range from 200 mm to 400 mm in diameter. The scalable vector format ensures sharp and accurate rendering in both printed and digital safety plans.
