Under the bill, which was just approved by the state Senate, the cost for a first offense would climb from $20 to $30. But the real cost would climb from $160 to about $200 when court fees are included.
Repeat offenders would pay about $370, which is up from about $280. Also, repeat violations would add points to drivers' records, potentially increasing their insurance costs.
Senators sent SB1310 to the governor's desk on a 28-9 vote.
Supporters of the bill say it will reduce the number of collisions by discouraging cellphone use. Critics, however, say the fines are too high.
