Vehicles are allowed to make a U-turn under the following circumstances: when there is a U-turn signal or sign, when left turns are permitted but there is no U-turn prohibition sign, at dashed lines, at yellow grid lines, and on the side of a green belt with dashed lines. U-turn signal or sign: When there is a U-turn signal at an intersection, a U-turn can be made when the U-turn signal is green. If there is a U-turn sign at the intersection or a U-turn indication on the lane, a U-turn can be made while ensuring the safety of oneself and others. No U-turn sign but left turns are permitted (no prohibition of U-turn signs): Vehicles can make a U-turn at intersections where left turns are allowed and there are no signs or markings prohibiting U-turns. It should be noted that the vehicle must proceed according to the left-turn lane signal without affecting the normal driving of other vehicles. If making a U-turn at an intersection with a left-turn waiting area, the vehicle can first enter the left-turn waiting area when the straight signal is green and then make the U-turn when the left-turn signal turns green. U-turn at dashed lines: U-turns are allowed at both white and yellow dashed lines. For double yellow lines (one solid and one dashed), check if your side is the dashed line; if it is, a U-turn can be made safely. If it is a solid line, a U-turn is not allowed. At intersections with double yellow lines (one solid and one dashed), a U-turn can be made on the dashed line side, but the vehicle must not cross the stop line ahead. U-turn at yellow grid lines: Parking is prohibited in yellow grid line areas, but as long as there is no central barrier, a U-turn can be made after yielding to normally moving vehicles. U-turn on the dashed line side of a green belt: When the front of the green belt is a dashed line, vehicles on that side can make a U-turn from there. When the front of the green belt is a solid line, vehicles must follow the traffic signal, cross the pedestrian crossing, and then make a U-turn. Driving over the solid line or the pedestrian crossing to make a U-turn is prohibited.

I've been driving for over a decade, and U-turns really depend on the location. At urban intersections, when there's a traffic light with a green arrow indicating a U-turn, it's definitely allowed. On roads without U-turn prohibitions, like wide multi-lane streets, just find a gap and turn slowly. But be careful—never make a U-turn on a pedestrian crossing or near a crossroad; safety comes first. I remember one night heading home when I accidentally made a U-turn on a one-way street and almost had an accident—luckily, I braked in time. Now, I always check the rearview mirror first to ensure no oncoming traffic before acting. U-turns save time but carry risks: beginners should practice more, and experienced drivers shouldn't get complacent. Dashcams can also help.

What are the methods to deal with excessive carbon monoxide in car exhaust?

Clean the three-way catalytic converter. Once this component is clogged or too dirty, it will lose its ability to convert carbon monoxide. Check the dashboard for any engine warning lights. If the air-fuel ratio of the engine cannot stabilize, incomplete combustion may occur.

What to Do When the Battery is Undercharged and Won't Charge?

Check if the fuse has poor contact and reconnect it. Replace the wiring. If the battery has been used for a long time, the electrolyte may decrease, and it needs to be refilled. Replace the battery.

What is the simplest way to reset a car's ECU?

Drive for a while to allow the car to reach normal operating temperature, then park and turn off the engine, shutting down all electrical devices in the car. Open the car's hood, locate the battery, and disconnect the battery's power cables. Wait for 10 minutes before reconnecting, then turn on the power without starting the engine and activate the car's electrical devices, waiting for 30 seconds. Remove the key, and the reset is successful.

What is the voltage of the ABS sensor connector?

The voltage of the ABS sensor connector is 5V to 8V, with an output voltage of 650mV to 850mV. During actual measurement, due to the fault protection function of the electronic stability control module, the voltage cannot be sustained after unplugging the ABS sensor connector, so voltage data cannot be used as a judgment criterion. The ABS sensor is an important component of the ABS system. ABS can maintain the directional stability of the vehicle during braking while driving, shorten the braking time and distance, and effectively prevent wheel lock-up and uncontrolled skidding during emergency braking, thereby enhancing the vehicle's controllability and making driving safer.
