Q
what is the recommended minimum following distance for commercial vehicles
I'm a seasoned industrial engineer with a keen interest in machine learning. Here to share insights on latest industry trends.
The Federal Motor Carrier Safety Administration (FMCSA) recommends at least a 4-second following distance for commercial vehicles in ideal conditions. However, this may need to be increased in unsafe conditions like heavy traffic, bad weather, or poor visibility.

The check engine light comes on when your car’s computer detects an issue within the powertrain. Here are steps on how you can potentially remove the check engine light:
1. Look for any obvious problems: Check if you have low oil or coolant. Inspect the gas cap to make sure it wasn't left loose after refueling.
2. Use a code reader: Use an onboard diagnostic code reader to read the error code. This code will give you an idea on what's wrong with the car.
3. Reset the code: After you've fixed the problem, you can use a code reader to reset the check engine light. If you don't have a code reader, you can usually disconnect the battery for a few minutes to reset the light, but this isn't recommended as it can wipe other settings in the car.
4. Take the car for a drive: After resetting, the light should be off. If it comes back on, this means there's still an issue.
5. Consult a mechanic: If you can’t find the problem or the light keeps coming on, it’s best to consult a professional mechanic who can diagnose the issue accurately and make the necessary repairs.
Note: Simply disconnecting the battery or using a code reader to remove the light WITHOUT fixing the underlying problem is not recommended, since the issue will most likely cause the light to come back on. It's also worth mentioning that in many countries it's illegal to sell a used car with a check engine light that's been tampered with. It's always best to fix the underlying issue causing the light to come on in the first place.
If the service engine light is flashing. it signals a more severe issue compared to a steady light. This means the engine may have caught fire and must be fixed immediately to avoid significant harm. Essentially. the blinking serves as a caution to address any potential damage to the engine or exhaust system parts like the catalytic converter. We advise minimizing driving and having your vehicle evaluated by a qualified mechanic right away. Neglecting this warning could lead to expensive repairs or compromise the safety of your vehicle.
Unseizing an engine that ran out of oil is challenging due to the damage caused by lack of lubrication. The process generally involves several steps. First, remove the spark plugs to relieve pressure. Then, manually turn the crankshaft with a breaker bar. If it moves, you might salvage the engine. Introduce a penetrating oil like WD-40 into the cylinders to help loosen any seized parts. Allow it to soak for several days. This method can sometimes free up minor seizures. However, if the engine is heavily seized, disassembly and inspection are necessary to assess and repair the damage. Components like pistons, bearings, and the crankshaft may need replacement. It’s vital to understand that engines running out of oil can suffer extensive damage, making recovery difficult and costly. Sometimes, replacing the engine might be more economically feasible than attempting to unseize the engine. Safety and proper diagnosis are paramount; consulting with a professional is recommended to evaluate the best course of action.
