Final answer:
A driver blocked from discounts due to a violation or accident can begin receiving them again after 3 years from the date of the incident, assuming no further violations.
Step-by-step explanation:
If a driver has been blocked from receiving a discount due to a violation in their Motor Vehicle Report (MVR) or an at-fault accident, and the block is for a period of 3 years, the date they can start receiving the discount again would be three years from the date of the violation or accident. Assuming there are no other violations or incidents that would extend the block. It's important for drivers to maintain a clean driving record to benefit from discounts offered by insurance companies.
