While driving, frequently monitor the movement of vehicles and pedestrians in the rearview mirrors. When reversing, use both the interior and exterior rearview mirrors. 2. Right-side A-pillar Blind Spot: Before making a right turn, check the road conditions on the right side. Activate the right turn signal and honk the horn, then proceed slowly while leaning forward to observe the right-side road conditions. When starting from a red light, do so slightly slower and avoid stopping beside large or tall vehicles on the right. Never rush to start when the light turns green. 3. Right-side B-pillar Blind Spot: Avoid making sharp lane changes. Before changing lanes, activate the turn signal and honk to alert nearby vehicles.

What Causes Jerking Sensation While Driving?

Jerking sensation during driving is caused by factors such as clogged air filters. Below are detailed explanations of the specific reasons for jerking sensation while driving: 1. Excessive carbon deposits: Heavy buildup of carbon deposits in the throttle body, fuel injectors, and intake manifold. This can cause jerking sensations, so regular carbon cleaning is recommended. 2. Low fuel quality: Substandard fuel quality leads to incomplete combustion, resulting in jerking. 3. Component failure: Issues with spark plugs, ignition coils, etc., causing misfires. These require professional inspection and timely repairs to prevent further safety hazards. 4. Clogged air filter: Long-term neglect of air filter cleaning allows excessive dust into the combustion chamber. The dust can easily adhere to various components when mixed with atomized fuel at the throttle body, leading to jerking.
