Core: Licence validity: age determines the term

The law ties the validity term to age at issuance: under 65 you get a standard 10 years; between 65 and 70 validity runs until your 75th birthday (never more than 10 years); from age 70 the term is 5 years. The book presents the same rule as an age-at-RENEWAL table — 'until 65 standard 10 years at renewal, between 65 and 70 max. 10 years, from 70 max. 5 years' — mathematically the same (65+10=75, 70+5=75), just a different starting point. The licence must never have lost its validity (the law); a statutory grace period after the end date does not exist. Two extra invalidating events, besides simply expiring: exchanging your Dutch licence for a foreign one, or committing fraud with the details on it. From age 75 an extra requirement is added, separate from the validity term itself: at renewal you must undergo a medical examination. That is not a fourth term, but a condition on top of the 5-year term that already applies from age 70.
