LINCOLN, Neb. (AP) — Getting approval for special license plates isn’t an easy task in Nebraska, prompting some lawmakers and groups to propose tinkering with the state’s process.

Under the current system, organizations can apply to the DMV for specialty plates, but they must have proof that at least 500 supporters will pay the yearly $70 fee.

Some organizations have struggled to obtain support. This session, groups have persuaded lawmakers to carry proposals directing the DMV to create specialty plates promoting an anti-abortion rights message and a breast cancer awareness theme.

Senators say license plates are harmless means of self-expression, but others say the state should not be responsible for authorizing promotion of controversial topics.
