If you are a truck driver, you should know that your safety, that of your passengers, and the road users depend on the condition of your vehicle. So, you must do everything possible to ensure that your truck is in top shape before you begin your journey. To know whether your truck has a mechanical problem, you don't have to be a professional mechanic. Rather, you only need to know how to identify a few signs which will indicate that your heavy vehicle is about to break down. When you identify any of the following signs, hire a professional mechanic for immediate repairs. 

1. Strange Noise When Braking

A heavy vehicle takes more time to stop after braking than a smaller vehicle. If the brakes fail when driving a heavy vehicle, you will have to rely on the emergency brakes or take other emergency measures to save your life and any passengers in the truck.  

One way to know that your brakes are failing is when you hear a strange sound when you step on the pedal. So, when you hear a squealing sound when you step on your truck's brakes, it's a clear indication that your heavy truck requires repairs. You should hire a professional mechanic to repair the faulty brakes before they fail completely. You don't want to cause a fatal accident due to failed brakes.    

2. Multiple Leaks 

Different leaks on the truck are a clear indication of a severe problem. The leaks are even more dangerous when they originate from the engine and are visible from underneath the truck. 

If you don't take prompt action when you notice a leak, your truck will eventually run out of oil, which might damage the engine. That is very dangerous because the truck can stall at any point, even in the middle of the road, which might cause a fatal accident. So, when you notice any leak, stop your truck and hire a professional mechanic to inspect and repair the leaking areas. 

3. Excessive Exhaust Smoke When Driving

The exhaust of your truck might produce white smoke when you start it. That is common, especially when there are freezing temperatures. However, if the smoke has a burning smell and you notice a black residue on the bumper area, you should take your vehicle to a mechanic before the problem worsens. 

To avoid inconveniences and ensure the efficiency of your truck, ensure that it's in tip-top condition before starting your journey. Watch out for the above signs above and hire a professional mechanic for truck repairs once you notice them. That guarantees your safety, as well as other passengers and road users.
