Final answer:
The official date used when calculating surchargeable conviction penalties is the date of violation.
Step-by-step explanation:
When calculating surchargeable conviction penalties, the official date of the offense is considered to be the date of violation. This is the date when the actual traffic violation or offense took place, not the date of conviction, the driver's license expiration date, or the date the conviction was reported to the driver's insurance company. It's the date recorded by the officer on the citation that will be used in determining penalties and increments to insurance premiums.
