What vehicles can a B2 driver's license drive?

B2 driver's license allows driving heavy-duty, medium-duty trucks, or large, heavy, and medium-sized special-purpose vehicles. 1. What are heavy-duty and medium-duty trucks: Heavy-duty and medium-duty trucks commonly seen on the road include dump trucks and large cargo trucks, while large, heavy, and medium-sized special-purpose vehicles refer to vehicles equipped with special devices or equipment, such as cranes, concrete mixer trucks, fire trucks, large sprinklers, etc. 2. Points to note: B2 license holders can drive trucks of any tonnage or length. It's important to note that the trucks referred to here must have the cab and cargo compartment on the same chassis. Separated trucks, commonly known as tractor-trailers or "semi-trucks," require an A2 license to drive. 3. Others: In addition, a B2 license also permits driving vehicles allowed by C1, C2, C3, C4, C5, and M driver's licenses.

What is the fuel consumption of the Highlander 2.0t?

The fuel consumption of the Highlander 2.0t is generally around 11 liters in urban areas and 8-9 liters on highways, depending on road conditions. Below is a related introduction to the Toyota Highlander: 1. Interior: The new vehicle features extensive use of high-quality leather wrapping on the steering wheel, instrument panel, door panels, and seats. It is the first to be equipped with a 12.3-inch color TFT multi-information display and a 12.3-inch color touchscreen navigation display. 2. Safety Features: Includes HUD triple-screen intelligent display, a streaming media rearview mirror, BSM blind-spot monitoring system, RCTA rear cross-traffic alert system, PVM panoramic monitoring system, and standard TPWS tire pressure monitoring system across all models. In terms of passive safety, all models come standard with seven SRS airbags.

Where is the Tire Pressure Monitoring Reset Button?

The tire pressure status can be viewed on the dashboard of the vehicle, which also includes a tire pressure monitoring reset button. Below is relevant information about automobiles: 1. The standard tire pressure is most suitable around 2.3-2.5pa: Tire pressure, strictly speaking, refers to the air pressure inside the tire. Nowadays, many tires are not filled with air. For these tires, the tire pressure requirements are more stringent. Tires filled with air are affected by seasonal changes. Moreover, tire pressure is closely related to the vehicle's performance, such as comfort and load capacity, and also affects the lifespan of the tire. Air pressure is the lifeblood of a tire; both too high and too low will shorten the tire's service life. 2. Low air pressure: This will increase the deformation of the tire body, making cracks more likely to appear on the sidewalls, and generate bending movements, leading to excessive heat, promoting rubber aging, fatigue of the cord layer, and breaking of the cords. It also increases the tire's contact area with the ground, accelerating wear on the tire shoulders. 3. High air pressure: This will cause excessive stretching and deformation of the tire cords, reducing the elasticity of the tire body and increasing the load the vehicle bears while driving. In case of impact, it may lead to internal cracks and blowouts. Additionally, high air pressure accelerates wear on the tire tread and reduces its pressure resistance.

The Real Cause of Engine Knocking?

Below are the causes of engine knocking: 1. Overly advanced ignition timing: To ensure that the piston receives power immediately upon entering the power stroke after the compression stroke, ignition typically occurs before the piston reaches top dead center. However, excessively advanced ignition can cause most of the fuel-air mixture to burn while the piston is still in the compression stroke. The remaining unburned mixture then undergoes extreme pressure and auto-ignites, leading to knocking. 2. Insufficient fuel cleanliness: Physical and chemical impurities in the fuel, including certain aromatic compounds, can also cause auto-ignition during the engine's compression process, resulting in knocking.

What to Do When Car Tires Are Underinflated?

For underinflated car tires, you can use an onboard air pump to inflate them and then drive to the nearest repair shop, or replace them with a spare tire before heading to the repair shop. The following precautions should be taken while driving: 1. Avoid sudden starts: Whether the car is empty or loaded, start smoothly at a low speed to prevent dragging the tires against the ground and reduce tread wear. 2. Maintain straight-line driving: On good roads, keep the car moving straight. Avoid swerving or making sharp turns unless necessary for passing or avoiding obstacles, as this can cause lateral cutting damage between the tire and rim. 3. Control speed appropriately: When descending long slopes, adjust your speed based on the slope's gradient, length, and road conditions. This helps avoid emergency braking, reduces tire wear, and ensures safer driving. 4. Use inertia when climbing: When going uphill, utilize the car's inertia, shift gears timely, and maintain adequate power. Avoid stopping and restarting to minimize tire wear. 5. Avoid high-speed turns: When turning, control your speed according to the curve. High-speed turns generate excessive centrifugal force, causing cargo to tilt and shift the center of gravity, overloading and dragging one-sided tires, accelerating wear, and potentially causing lateral cutting damage by the rim. 6. Avoid emergency braking: In complex driving conditions, maintain an appropriate speed to reduce frequent and emergency braking, which can cause sliding friction between the tires and the ground, leading to severe tread wear. 7. Slow down on rough roads: Drive cautiously, choose the best path, and after passing, stop to check for stones stuck between dual tires, removing them promptly if found. 8. Park safely: Develop a habit of coasting to a stop safely. Before parking, choose a flat, clean, and oil-free surface, ensuring all tires land smoothly. Especially when parking overnight with a loaded vehicle, select the parking spot carefully and, if necessary, lift the rear wheels.

Can You Make a U-Turn at an Intersection Where Left Turns Are Prohibited?

You cannot make a U-turn at an intersection where left turns are prohibited. Here are some precautions for making a U-turn: 1. Wide roads: You can make a wide turn by first positioning the vehicle toward the opposite side of the U-turn, turning on the signal, and after confirming safety, turning the steering wheel fully to complete the U-turn. 2. Narrow roads: Use a combination of moving forward and backward to make the U-turn. When turning for the U-turn, as the front wheels approach the roadside or the front of the vehicle nears an obstacle, press the clutch, lightly apply the brake, and before the vehicle comes to a complete stop, quickly turn the steering wheel in the opposite direction to steer the front wheels toward the new direction needed for reversing, then immediately bring the vehicle to a stop.
