Subject 3 straight-line driving should be maintained below 40 km/h. The test requirements for straight-line driving are that within the test driving distance, the deviation of the vehicle body from the distance to the side lines on both sides must not exceed 30 cm (meaning the vehicle body must remain almost perfectly parallel to the side lines during driving), and the steering wheel must not swing more than 5 degrees. Introduction to Subject 3: Subject 3 includes the road driving skills test and the safety and civilized driving knowledge test. It is part of the motor vehicle driver's license assessment and is the abbreviated name for the road driving skills and safety and civilized driving knowledge test in the motor vehicle driver's examination. The content of the road driving skills test varies for different types of vehicles eligible for driving. Subject 3 test content: The road driving skills test in Subject 3 generally includes: vehicle preparation, light simulation test, starting, straight-line driving, gear shifting operations, lane changing, pulling over, driving straight through intersections, left turns at intersections, right turns at intersections, passing through pedestrian crossings, passing through school zones, passing through bus stops, meeting vehicles, overtaking, U-turns, and night driving. The safety and civilized driving knowledge test generally includes: requirements for safe and civilized driving operations, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations like tire blowouts, and post-accident handling knowledge.

What tire pressure is prone to blowouts?

When the tire pressure exceeds 30% of the specified value, the probability of a blowout increases significantly. The specified value can be found on the car's door or fuel tank cap, and it varies depending on the vehicle. Here are specific details about blowouts: 1. A blowout refers to the phenomenon where a tire suddenly loses air and deflates in an extremely short time (generally less than 0.1 seconds) due to rupture. Blowouts are one of the frequent accidents for cars in summer, mostly caused by improper tire maintenance by the owner. 2. When a car is driving at high speed (over 120km/h), insufficient tire pressure can easily cause "harmonic vibration" in the tire body, leading to significant resonant forces. If the tire is not strong enough or already has damage, it is prone to blowouts.

How Many Cubic Meters Can a Concrete Mixer Truck Carry?
