Leaks under the truck—oil, coolant, brake fluid, or fuel—are early signs of mechanical failure. Unusual smells (burning, sweet, or chemical) can indicate overheating or leaks.
Hungary’s NKH inspections check for fluid leaks during roadside checks.
Germany’s TÜV inspections require leak-free systems for certification.
Fuel or brake fluid leaks pose fire and safety hazards.
Coolant leaks can cause engine overheating in alpine regions.
Early detection prevents environmental violations and mechanical damage.
Purpose for Training: To help drivers perform visual and smell-based checks during pre-trip inspections and report leaks before they become dangerous.
