Q: Recently I was tagged on Interstate 80 for not moving over to the left lane to give maximum space to a highway patrol car whose officer had pulled a motorist over on the right shoulder and had its lights flashing. It’s my first moving violation since 1978.

The officer was not in any mood to let me off with a warning and slapped me with a $195 ticket. When I asked how long this rule had been on the books, he replied about seven years and said that it has been spreading from state to state.
