FYI. When you have 20 years of safe driving and have an accident, it doesn't go back to zero. UPS is mis-leading the general public (imagine that).
Correct. It is 20 years without an accident. Not necessarily 20 consecutive years.
If you have an accident within the first 5 years, you start from scratch. Once you get 5, you can never have less than 5.
If you have, let's say, 20 and a half years safe driving and you have an accident, you still have your 20 and need to go 1 year from the date of the accident and you will then have 21.
To say someone has 20 years of safe driving, people would think that he drove the past 20 years without an accident. Not necessarily.
He could have had an accident yesterday but UPS will still say he has 20 years of safe driving.
He did drive 20 years without an accident during those 20, but he may have had a total of 30 years driving.
He actually could have had 10 accidents, but the public thinks this guy is very safe because he has 20 years of safe driving.
