Abnormal noise when accelerating a motorcycle is usually caused by excessive valve clearance or loose components. Here are specific solutions: 1. Excessive valve clearance: The noise during acceleration is caused by excessive valve clearance, which can be resolved by readjusting the valve clearance. A "clanking" sound under load during acceleration may result from poor-quality gasoline or a lean air-fuel mixture due to insufficient fuel supply from the carburetor. This can be fixed by using standard gasoline and cleaning the carburetor. 2. Loose components: If the noise is due to loose parts, it is advisable to have the motorcycle inspected and repaired at a service center to prevent minor issues from escalating into major accidents, thereby reducing potential economic losses.

Can You Stop During a Right-Angle Turn?

You cannot stop during a right-angle turn. You may stop and wait before the right-angle turn sign, but once you have entered the right-angle turn section, stopping is not allowed. Stopping midway will be considered a failure. Right-Angle Turn Scoring Criteria: If the wheels run over the road edge line, 100 points will be deducted; if the turn signal is not used or is used incorrectly before the turn, or if it is not turned off after the turn, 10 points will be deducted; if the vehicle stops for more than 2 seconds midway, 5 points will be deducted per occurrence. Key Points for the Right-Angle Turn Test: Drive the vehicle along the designated route, make a left right-angle turn without the wheels touching the road edge line, and do not stop midway. Activate the left turn signal in advance before turning and turn it off after completing the turn. Precautions for Right-Angle Turns: The timing for turning the steering wheel is crucial and very brief. Turning the wheel too early will cause the rear wheel to run over the inner corner of the lane, while turning it too late will cause the front corner of the car to exceed the outer edge line of the lane, leading to complications if missed. Also, do not forget to turn off the turn signal.

Which Xenon Headlights Are Brighter?

They are generally similar, as xenon headlights are inherently brighter than standard halogen bulbs. There are two types available: 35W and 55W, with 35W being more commonly used. The above refers to wattage, but there's also color temperature to consider. Higher color temperature doesn't necessarily mean brighter light; it just changes the color. Common color temperatures include 2400K, 4300K, and 600K, which correspond to golden yellow, warm white, and ultra-white light, respectively. The higher the color temperature, the worse the light penetration, meaning in rainy or foggy conditions, lower color temperature lights provide better visibility, while higher color temperatures can result in a blinding white haze. Below are some recommendations for xenon headlight modifications: 1. A cost-effective option is to simply replace the bulbs without modifying the entire headlight assembly. For low and high beams, you can choose between 4300K or 6000K, with 4300K recommended for a milder effect—though it can still be glaring when facing oncoming traffic. Fog lights should always use 2400K golden yellow bulbs, as they make raindrops appear like golden particles, enhancing visibility. However, one drawback is that without a lens, the low and high beams may scatter more. 2. Another modification involves improving focus capability to achieve greater brightness, but this comes with higher modification costs.

What is the driving sequence for going straight, turning left, and turning right?

The driving sequence for going straight, turning left, and turning right is as follows: left-turning vehicles yield to oncoming vehicles going straight, and right-turning vehicles yield to oncoming vehicles turning left or going straight. When two vehicles are both going straight, the vehicle coming from the right side of the road has the right of way, and the vehicle on the left yields to the vehicle on the right. When passing through an intersection, drivers must strictly adhere to traffic signals and road markings. If a vehicle goes straight through an intersection from a left-turn lane, it will be penalized for not following the designated lane. If a vehicle does not drive in the correct lane on highways or urban expressways, the driver will receive 3 demerit points and a fine. Here is more information about driving: Designated lanes: At intersections with designated lanes, enter the lane corresponding to your intended direction of travel. Entering a roundabout: When preparing to enter a roundabout, yield to vehicles already inside the roundabout. When turning left: Turn from the left side of the intersection center point. Use turn signals when turning, and switch to low beams when driving at night.

Does Adding a License Affect a Long-Term Driver's License?

Adding a license can affect a long-term driver's license. If you hold a C1 driver's license and apply to add a motorcycle license, it will not affect the seniority of the C1 license or the renewal of a long-term driver's license. However, if you apply to add a B-class license or above to your C1 license, it will directly impact the seniority of your driver's license. Below are the requirements for adding different types of driver's licenses: Conditions for adding an A1 driver's license: You must have held an A2 license for at least 1 year, or a B1/A3 license for at least 2 years, or a B2 license for at least 3 years, with no record of accumulating 12 penalty points in the most recent scoring cycle, to directly add an A1 driver's license. Conditions for adding an A2 driver's license: You must have held an A1 license for at least 1 year, or a B1/B2 license for at least 2 years, with no record of accumulating 12 penalty points in the most recent scoring cycle, to directly add an A2 driver's license. Conditions for adding an A3 driver's license: You can directly apply for the A3 license without needing to add it to an existing license. Alternatively, you can add an A3 license if you have held any driver's license for at least 1 year with no record of accumulating 12 penalty points.
