can you drive your car the day rego is due nsw

Short answer: yes—In NSW your rego remains valid until 11:59pm on its expiry date, then it turns into a pumpkin at midnight.

There’s no grace period after that, and unregistered means uninsured too—quite the double whammy. Sort your CTP Green Slip and eSafety check ahead of time so renewal is a five‑minute job, not a scavenger hunt. If you miss the date, park it and renew before you drive again.
