EPA is actually the abbreviation for the United States Environmental Protection Agency. This agency is responsible for the EPA-Ratings vehicle driving cycle tests, which include environmental simulations of urban road conditions, highway conditions, and mixed road conditions. The testing conditions are very stringent, aiming to closely approximate real-world scenarios. Relevant information about speed limits is as follows: Introduction to speed limits: Speed limits generally refer to regulations that set a specific range of driving speeds for a certain length of road. Purpose of speed limits: The main objectives are to preemptively remind drivers to reasonably control their speed in subsequent road sections ahead, prevent the dangers of speeding, and ensure driving safety. Speed limits are an indispensable and most crucial aspect of road transportation safety.

Which province does a license plate starting with 'Fang' belong to?

License plates starting with 'Fang E' do not exist in reality. The 'Fang E' license plate is a prop used in TV dramas and is purely fictional, so such license plates do not exist in real life.

Is N Gear the Neutral Gear?

N gear is indeed the neutral gear, which exists in both automatic and manual transmissions. The N gear is positioned between the R (Reverse) and D (Drive) gears on the gear shift console. The function of the N gear is to disconnect the power transmission between the input and output shafts of the transmission. The N gear can be used when parking for a short duration. The methods for using the N gear are as follows: 1. Under safe conditions, any forward gear can be shifted to N gear at any time, but shifting from P (Park) or R (Reverse) to N gear requires pressing the brake pedal first; 2. Normally, the vehicle should be brought to a complete stop by pressing the brake before shifting from N gear to any other gear. However, in special circumstances, the N gear can be directly shifted to a forward gear, though this will cause a strong impact and may damage the transmission; 3. In most automatic transmission models, the ignition key must be turned to the second position to power on the vehicle before the gear shift lever can be moved from P gear to N gear.

How to Find the Positive Terminal of the Turn Signal?

To locate the positive terminal of the turn signal, follow these steps: 1. Turn on the turn signal; 2. Use a multimeter to systematically check for a 12V voltage with a regular on-off pattern—this will be the positive wire for the left and right turn signals. The turn signal is a frequently used light by drivers, clearly indicating the intended direction of travel to surrounding vehicles. In a car, the turn signal is located on the left side of the steering wheel. When needing to signal a turn, move the light lever up or down—up for the right turn signal and down for the left. Specific situations requiring the use of turn signals include: 1. Overtaking; 2. Changing lanes; 3. Making a U-turn; 4. Exiting a roundabout; 5. Pulling over to park; 6. Entering a highway.

How to Solve Rear Wheel Locking After Releasing the Handbrake?

The solutions for rear wheel locking after releasing the handbrake are: 1. Force start by stepping hard on the accelerator; once the rear wheels move, the locking can be released. 2. Remove the tire and tap the brake drum with a hammer or similar tool to loosen the contact surface between the brake drum and the brake pads. The reasons for rear wheel locking after releasing the handbrake include: 1. The car's handbrake cable not retracting; 2. The car's brake caliper not retracting; 3. The brake friction pads being frozen. Other situations of car wheel locking include: In cars without ABS, if the brake pedal is pressed hard while driving, the wheel speed will rapidly decrease. When the braking force exceeds the friction between the wheel and the ground, the wheel will lock. A completely locked wheel reduces the friction between the tire and the ground, and in severe cases, dangerous phenomena such as skidding, fishtailing, and sudden spinning may occur.
