What should you check to ensure you have enough space over your vehicle?

To ensure you have enough space over your vehicle, it's essential to check elements like wires, signs, trees, and air conditioning units. These obstacles can limit the vertical clearance necessary for your vehicle, particularly if it is taller than standard vehicles, such as vans or trucks. By being aware of these overhead structures, you can prevent potential issues such as collision with low-hanging power lines or branches, which could lead to damage to your vehicle or create safety hazards.

Considering other options, focusing only on road conditions would not address vertical clearance and would overlook crucial overhead risks. Checking only height restrictions is not comprehensive, as it does not take into account the presence of utility wires and other obstacles that can vary widely in different environments. Lastly, paying attention solely to posted speed limits is necessary for safe driving but does not pertain to checking the overhead space required for your vehicle. Therefore, properly assessing the presence of tall structures and obstacles is vital for safe maneuvering, especially in areas where vertical clearance may be compromised.
