Its function is to provide and confirm the piston position signal to the vehicle's computer ECU, thereby determining the ignition timing and sequential fuel injection of the engine. Taking the 2021 Toyota Corolla as an example, it belongs to the compact car category, with body dimensions of: length 4635mm, width 1780mm, height 1455mm, wheelbase of 2700mm, fuel tank capacity of 50 liters, and trunk capacity of 470 liters.

Does crossing the line during a yellow light turning red count as running a red light?

Crossing the line during a yellow light turning red is considered running a red light. If the vehicle has just crossed the stop line when the light turns red but stops immediately, this act of running a red light will not be penalized. However, if there is noticeable movement after crossing the line, penalties will be imposed. The electronic monitoring system captures three photos as evidence of running a red light: the vehicle crossing the stop line, followed by two more photos showing the vehicle in the middle of the intersection and reaching the opposite side. Below are solutions for mistakenly running a red light: 1. Stopping immediately after mistakenly running a red light can avoid penalties. When capturing violations of running a red light, intersection cameras typically take three photos as evidence. 2. Appeal for mistakenly running a red light: If the violation was not due to the driver's own fault, in addition to early corrections through legal reviews, appeals can also be made through administrative reconsideration or administrative litigation.
