Constituent saves Morrison from car fiasco

Treasurer Scott Morrison has a lot on his mind a week out from the federal budget.

Which explains a seniors moment on Anzac Day.

Mr Morrison forgot to apply the handbrake when he parked his car at a dawn service he attended in his southern-Sydney electorate.

A constituent alerted him to the error just as the car began to roll away. Fortunately, no harm was done.

"It was early in the morning and I appreciate the help from one of my good shire mates," Mr Morrison told Ray Hadley on radio 2GB on Tuesday.

"It was not one of my finest driving moments."

Hadley warned the treasurer there would be many similar moments as he gets older, but Mr Morrison is not too worried.

"(My wife) Jen can drive. She's a much better driver than me."
