Is the road administration's towing service free if a vehicle breaks down on the highway?

When a vehicle breaks down on the highway, the road administration provides free towing services. This free towing service aims to prevent prolonged vehicle stoppages due to paid towing negotiations or drivers attempting repairs to save costs. It effectively ensures the safety and smooth flow of traffic on the main highway lanes and reduces the risk of secondary accidents. Precautions during towing: Prefer towing bars: If the trailing vehicle has brake issues or towing is required on icy/snowy roads, a towing bar should be prioritized. Rigid towing bars prevent situations where excessive pulling by the lead vehicle or sudden braking could cause the towed vehicle to lose control and collide. Even under normal circumstances, using a towing bar is safer. Select appropriate towing hooks: The towing hook must not merely "hook on" but should be securely fastened and properly installed. Always double-check the hook connection before towing. A poorly secured hook that disengages mid-tow creates significant complications. Plan the route and maintain communication: Choose a towing route with lighter traffic, better road conditions, and shorter distance. Avoid areas with potential hazards like pedestrian zones, logistics hubs, commercial centers, or underground parking lots to minimize secondary accident risks. Ideally, use walkie-talkies for constant communication to address emergencies promptly. At minimum, coordinate via horn signals. Control speed and distance: Towing requires particular attention to speed management and inter-vehicle spacing, as improper handling easily leads to accidents. Never tow at normal driving speeds—maintain a maximum speed of 20 km/h, never exceeding 30 km/h, since non-running vehicles lack vacuum-assisted braking. Maintain an optimal distance of 5-11 meters between vehicles, allowing adequate reaction time if the lead vehicle brakes suddenly.

How many points are deducted for stopping less than 50cm on the slope?

For the driving test subject 2 (slope driving), stopping between 30cm and 50cm from the designated line will result in a 10-point deduction. Slope parking test requirements: This actually includes two test items: first is the designated parking on the uphill slope, followed by starting the vehicle on the slope. For designated parking, the vehicle's front bumper must stop at the middle of the yellow parking line, with the bumper not exceeding or falling short of the yellow line by more than 50cm. The right wheels must stop between the edge yellow line and white line (30cm width). For slope starting, the vehicle must not roll back more than 30cm. Slope parking scoring criteria: Parking outside the 50cm range from the designated line: 20-point deduction; Rolling back more than 30cm: failure; Engine stalling: 20-point deduction; Parking with right side exceeding 30cm range: 20-point deduction; Failing to leave the starting position within 60 seconds after engaging gear: failure.

What is the charging principle of a car battery?

The charging principle of a car battery is the process of mutual conversion between chemical energy and electrical energy. Below is an introduction to car battery charging: Principle: Chargers generally adopt a four-stage charging method. When the battery level is low, a constant current charging method is used, meaning charging is performed at a constant current. At this stage, the energy consumed by the control circuit is relatively small compared to the charging process. When the voltage reaches a certain value, it switches to a constant voltage charging method. As the battery voltage rises, the charging current gradually decreases until the charging voltage matches the battery voltage. During this process, the proportion of energy consumed by the control circuit gradually increases. During the constant voltage charging process, constant current charging is performed again (the more stages there are, the higher the efficiency, but the more complex the control). When the charging voltage matches the battery voltage, it enters a trickle charging stage. The equilibrium voltage at this stage is generally designed to be the battery's termination charging voltage (1.2 times the battery's rated voltage) plus the voltage drop caused by overcoming the battery's internal resistance under this current (different batteries have different internal resistances). Process: The battery uses lead plates filled with sponge-like lead as the negative electrode, lead plates filled with lead dioxide as the positive electrode, and a 22% to 28% dilute sulfuric acid solution as the electrolyte. During charging, electrical energy is converted into chemical energy, and during discharging, chemical energy is converted back into electrical energy. When the battery discharges, the metallic lead is the negative electrode, undergoing an oxidation reaction and being oxidized into lead sulfate; lead dioxide is the positive electrode, undergoing a reduction reaction and being reduced into lead sulfate. When the battery is charged with direct current, lead and lead dioxide are generated at the two electrodes respectively. After the power source is removed, it returns to its pre-discharge state, forming a chemical battery.

What are the reasons for the weak acceleration of the 09 Passat EFI model?

09 Passat EFI model may experience weak acceleration due to a dirty throttle body or a clogged fuel filter. Relevant information about the Passat is as follows: 1. Exterior: The Overcomer model made some improvements based on the Santana 2000. In terms of appearance, the Overcomer basically inherited the design of its predecessor, the Santana 2000. To summarize in one sentence: a complete transformation. The most notable change is the front-end redesign: at first glance, the Overcomer may not seem to have many exterior modifications, but its front grille has become wider and more substantial, featuring the classic Volkswagen V-shaped smile. A major improvement in the front is the fully integrated headlights, with the spherical shape of the high-beam lights inside, creating a harmonious look. The front lighting system uses round projection lamps, with a horizontal strip-shaped position light at the bottom to reflect light from all directions, enhancing nighttime visibility and safety. The engine hood has been redesigned, with a prominent front edge that gives a fuller appearance. The taillights also feature a new design: the integrated taillight cover has a simple and clear color layout, and the license plate has been moved down to the newly designed rear bumper, emphasizing a more stable visual effect. The high-brightness Volkswagen logo once again becomes the focal point. The side anti-scratch strips have been slightly lowered, and the metal trim strips below the waistline of the standard Passat model have been replaced with new glossy trim strips at the lower edge of the door panels, giving the side a more stable look. 2. Interior: The light-colored leather interior, though not luxurious, features a soft design that is visually appealing. The leather seats offer better support compared to the previous model. The Passat-style three-spoke steering wheel and the simple yet elegant lines of the center console give a well-organized feel. The layout of the center console remains largely unchanged, but the craftsmanship has improved, with buttons and knobs offering a comfortable touch. In terms of seating space, the Overcomer largely follows the design of the Santana 2000, with the addition of a retractable center armrest in the rear seats. The Overcomer provides the driver with a left-side dual-curvature exterior rearview mirror, offering a wider field of vision and improving driving safety. The electric trunk opening switch uses the latest encoded wireless technology.

Is U-turn allowed at circular traffic lights?

U-turn is allowed at circular traffic lights. According to the "Regulations for the Implementation of the Road Traffic Safety Law": Motor vehicles can make U-turns at locations where there are no prohibitory signs or markings against U-turns or left turns, provided that they do not hinder the normal passage of other vehicles and pedestrians. Circumstances allowing U-turns: Presence of U-turn traffic lights or signs: U-turns are permitted when there are traffic lights allowing U-turns at the intersection. No U-turn signs but left turns allowed (no prohibitory U-turn signs): If making a U-turn at an intersection with a left-turn waiting area, you can first enter the left-turn waiting area when the straight-through light is green, and then make the U-turn when the left-turn light turns green. U-turns allowed at dashed lines: Whether it's a white dashed line or a yellow dashed line, U-turns are permitted. For double yellow lines with one solid and one dashed, check if your side is the dashed line; if so, a U-turn is allowed safely. If it's a solid line, U-turns are prohibited. At intersections with double yellow lines (one solid, one dashed), U-turns can be made on the dashed side, but you must not cross the stop line ahead. U-turns allowed at yellow grid lines: Parking is prohibited in yellow grid areas, but as long as there is no central barrier, you can make a U-turn here after yielding to normally moving vehicles. U-turns allowed on the dashed side of green belts: When the front of the green belt is a dashed line, vehicles on that side can make U-turns from there. When the front of the green belt is a solid line, vehicles must follow traffic light instructions, cross the zebra crossing before making a U-turn, and must not cross the solid line or the zebra crossing for the U-turn. Precautions for U-turns: When making a U-turn, you should activate the left turn signal in advance, and the maximum speed should not exceed 30 kilometers per hour. Do not hinder the normal passage of other vehicles and pedestrians.
