My little 14 foot singl-axle trailer in TX, that I use for hauling branches, wood, feed, lawn mower, etc is $61.25 a year.
Registration fee: $45
County road bridge add-on: $10
Child safety fund: $1.50
Handling fee: $4.75
The child safety fund is just another money grab:
Under the law, a county may keep up to 10 percent of the funds raised, plus an amount proportional to the population in unincorporated areas of the county.
The remainder of the money is distributed to municipalities in the county proportional to their populations.
The money must be used for a school crossing guard program, if the city or county operates one, or for programs that promote safety, health or nutrition among children, according to the law.
