Family location sharing works best as an agreement, not a rule handed down. Teenagers can usually work out how to switch it off, so the aim is for them to not want to.
Make it two-way
If you want to see where they are, share your own location with them too. That turns it from monitoring into a family arrangement.
Agree what it is for, and what it is not for
For example, it is for late journeys home, travelling alone, and emergencies. It is not for checking up on them every hour or questioning every stop. Write the agreement down if that helps.
Do not use it to catch them out
If the map shows something that worries you, talk about it calmly. Using location data as a "gotcha" is the quickest way to make someone turn sharing off.
Plan to review it
Pick a point to revisit the arrangement, such as a birthday or when they start college. Giving teenagers more privacy as they get older is part of the deal.
