I just found out that the fine for using a cellphone in Mexico City is now over 4,000 pesos, and honestly, that's quite steep. It turns out that since February, all traffic sanctions have been adjusted, and the gap between what is charged in the capital versus Jalisco is huge. Here in Mexico City, it costs between 3,500 and 4,100 pesos if you're caught with your phone, while in Jalisco, the maximum is 2,900 pesos for the same infraction. The difference is that the capital's regulations punish more severely, assigning up to 35 UMAs compared to 15 in Jalisco. What's interesting is that there is a discount for early payment in the capital. If you pay within the first 10 business days after being notified, you get a 50% reduction on the fine. However, in Jalisco, the final amount depends on what the officer considers at the time of issuing the ticket. And well, the important thing to know is that the prohibition is total. It doesn't matter if you're at a traffic light, in traffic, or even stopped—you can't manipulate the cellphone. It is only allowed if you use an integrated hands-free system. So if you drive in either of these states, it's better to keep your phone stored because the cellphone fine is serious on both sides.
