What are the hazards of driving over speed bumps at 70 km/h to a car?

Driving over speed bumps at 70 km/h affects the car's tires, suspension, and ride comfort. Impact on tires: Tires are the only part of the car that comes into contact with the ground, and any changes on the road surface first affect them. Tires are wear-and-tear parts, and driving conditions directly influence their lifespan. Frequently passing over speed bumps at high speeds may damage the tire surface and even cause the wheel rim to deform due to compression. Impact on suspension: When a vehicle passes over speed bumps at high speed, the suspension system is subjected to impacts several times or even dozens of times greater than during normal driving. This severely affects the lifespan of components such as shock absorbers, springs, and brackets. Strong impacts can also damage the chassis, posing a threat to the brake lines, fuel tank, fuel pipes, exhaust system, and engine oil pan located underneath the car. This threat is directly related to the vehicle's driving safety. Impact on comfort: When a vehicle quickly passes over speed bumps, the first reaction of passengers inside is the jolt, which can be very uncomfortable. For vehicles with stiffer suspensions, rear-seat passengers may even bounce up, potentially hitting their heads against the roof and causing injury. Additionally, this action can stir up dust inside the car, polluting the air and affecting the health of the occupants.

Can You Drive with High Engine Coolant Temperature?

You should not continue driving with high engine coolant temperature. The normal operating temperature for an engine is 90 degrees Celsius, which ensures optimal engine performance and fuel efficiency while reducing wear and extending service life. Below are key points about engine overheating: 1. Both excessively high and low engine temperatures can lead to increased wear and reduced power output. Particularly, prolonged operation under high temperatures can severely damage the engine, potentially causing complete engine failure. 2. When the high-temperature warning light comes on, first reduce speed and pull over to the roadside. Do not immediately turn off the engine, as extreme heat causes components like pistons, cylinder walls, and crankshafts to overheat, thinning the engine oil and compromising lubrication. 3. Shutting down the engine at this point while components are thermally expanded (with minimal clearances) may cause soft metal parts to detach or even result in piston seizure. Therefore, after noticing overheating, maintain idle operation temporarily to facilitate cooling instead of turning off the engine immediately.

How often should platinum spark plugs be replaced?

Platinum spark plugs should generally be replaced every 60,000 kilometers. Below are the specific details: 1. The replacement interval should be analyzed flexibly based on actual conditions. If the vehicle is under warranty, strictly follow the replacement schedule specified in the maintenance manual. Failure to adhere to the manual's replacement guidelines may give the manufacturer grounds to deny warranty claims if engine issues arise. For vehicles out of warranty, spark plugs can be replaced every 40,000 to 50,000 kilometers. 2. Spark plugs are divided into two types: standard copper-core (nickel alloy) spark plugs and precious metal spark plugs (platinum, iridium). The main difference lies in the electrode material. Standard spark plugs have a service life of 30,000 kilometers, platinum spark plugs last up to 60,000 kilometers, and iridium spark plugs can endure up to 80,000 kilometers.

What to Pay Attention to When Applying for Driving School

Here are the things to pay attention to when applying for driving school: 1. Whether the driving school has its own regular training ground and where it is located (avoid signing up with Driving School A but practicing at Driving School B), and whether it is a private car owner affiliated with the driving school; 2. The reputation of the driving school, its pass rate, and the integrity of the instructors—these will directly affect how much you will spend on driving lessons; 3. Whether the driving school charges a one-time fee. Legitimate driving schools usually charge slightly higher fees, while some schools attract students with low prices but charge various additional fees during training, ultimately costing you thousands more than schools with higher initial fees; 4. When signing up, be sure to visit the training ground. Legitimate driving schools may even offer free trial lessons; 5. Whether additional fees are charged for using the training ground or for retaking lessons if you fail the test; 6. Whether the fee details are clearly stated in the contract and whether the contract uses the standardized numbered version issued by the transportation authority. Some branch schools use simplified contracts printed on A4 paper, and some privately affiliated schools may not even sign contracts, leaving students' rights unprotected.

What Causes Heavy Steering Wheel Feel?

Here are the reasons why the steering wheel feels heavy: 1. Insufficient power steering fluid/oil. Power steering fluid is a medium oil used in the car's power steering pump, which transmits steering force and provides cushioning. The power steering fluid needs to be replaced regularly, and checked for leaks. When the power steering fluid is insufficient, the steering will feel heavy and stiff. 2. Low tire pressure. Low tire pressure increases the contact area between the tires and the road surface, leading to greater friction and making steering more difficult, resulting in a heavy steering wheel, which is not conducive to driving safety. 3. Steering gear or power steering pump failure. The steering gear and power steering pump also affect the car's steering. Any malfunction in these two critical components can cause steering difficulties.

What to Do If Your Vehicle License Plate is Cloned?

Here are the steps to take if your vehicle license plate is cloned: 1. Gather evidence that the vehicle owner was not present at the scene. 2. Visit the traffic police department to verify the violation information. 3. Submit an appeal to the traffic management department. 4. Apply for a replacement of the vehicle license plate number. Here are the legal bases: 1. If the motor vehicle license plate or registration certificate is lost, missing, or damaged, the vehicle owner must apply for a replacement or reissuance at the local vehicle management office. When applying, the vehicle owner must fill out an application form and submit proof of identity. 2. The vehicle management office shall review the submitted proofs and documents, retrieve the license plate or registration certificate that is not lost, missing, or damaged, reissue or replace the registration certificate within one day from the date of acceptance, and reissue or replace the license plate within fifteen days from the date of acceptance, with the original license plate number remaining unchanged. During the period of reissuance or replacement of the license plate, a temporary license plate valid for no more than fifteen days shall be issued.

How Many Years Should Tires Generally Be Used Before Replacement?

Automobile tires can generally be used for 3-5 years, with a recommended mileage not exceeding 60,000 kilometers. The service life of car tires is directly related to the driver's driving habits and the driving environment. During daily vehicle use, it is necessary to make reasonable judgments about the tires. If the tires are no longer usable, they should be replaced promptly. The following are indicators for tire replacement: 1. Sidewall bulging: If bulging appears on the sidewall of a car tire, it is necessary to replace the tire immediately. Sidewall bulging is difficult to repair and indicates that the tire's cords have broken. This can lead to a blowout at any time while driving, so timely replacement is essential to avoid compromising driving safety. 2. Tire cracks: Tire cracks are relatively common during daily vehicle use. These cracks can vary in length and depth, requiring careful assessment. If the condition of the tire cannot be determined, it is recommended that the owner visit a 4S shop or a professional auto repair shop for inspection. Severe tire cracks can lead to bulging and eventually cause a blowout. 3. Tire wear indicators: Car tires have wear indicators, which mark the limit of tire wear. If the tire wear reaches this indicator, the tire should be replaced immediately. Such tires pose significant safety hazards. Even on dry roads, the braking distance will increase, and on wet or slippery roads, they are prone to skidding or brake failure.
