A driver does 20 minutes of in-scope assimilated driving during a day that is otherwise local domestic work. What does that mean for records and limits?

1. The short period can be ignored
2. The driver must keep assimilated/AETR records for the day and count domestic duty as other work for those records
3. Only GB domestic records apply because most of the day was local
4. The tachograph can be switched off after 20 minutes
