THE LTA has booked up to 70 drivers in Suva for using mobile phones while driving.
Authority spokesman Iliesa Sokia said the past three weeks had been focused on education and encouragement, and the enforcement began this week.
"For the last three weeks, we concentrated on education and encouragement and we have started the actual booking this week," Mr Sokia said.
"In the operation itself, we are tasked to book at least 10 drivers in a day. This doesn't include other daily operations by the LTA officials and police, there could be more."
He said the booking was a result of concerted effort by LTA enforcement officers and road marshals who had been working together since the launch of the Triple E campaign.
"The law says any two-way communication device is not allowed to be used by a driver while behind the wheel," he said.
