Mexico has published rules governing the use of drones, allowing people to operate the smallest drones in daylight without a permit but with safety rules.
Mexico's Transportation Department has established three classes of drones according to size.
The smallest weigh 2 kilograms (4.4 pounds) or less. They won't require a permit, but like all other drones must stay 9.2 kilometers (5.72 miles) away from airports and 900 meters (985 yards) from helicopter pads.
Medium-size drones are defined as weighing between 2 kilograms and 25 kilograms (55 pounds), and require a permit unless they're . . .
