How large a vehicle do I need to stop?
What level of security should your vehicle-stopping bollard provide? The first part of this question is determined by the size of vehicle most likely to challenge your bollard. Common vehicle types and weights are below.
| Compact | 3,000 to 4,500 |
| Mid-size | 4,500 to 5,500 |
| Light trucks | 5,000 to 7,000 pounds |
| Minivans | |
| SUVs | |
| Larger personal trucks | 7,500 to 12,000 |
| Cargo trucks | 12,500 to 15,000 |
Perhaps consumer vehicles - smaller than an SUV - frequent your site. Do cargo trucks cross or draw near to pedestrian paths on your site? Don't take into consideration vehicles that are completely isolated from pedestrians and valuable property.
