30 Excuses for Being Late That Actually Work

The best excuses for being late are simple, believable, and impossible to check — think transport delays, a dodgy alarm, or a last-minute emergency at home. Below are 30 excuses for being late that actually hold up, grouped by situation. Need one on the spot? Our Excuse Generator spins a fresh, plausible reason every tap.

What is a good excuse for being late?

A good excuse for being late is one that's believable, hard to disprove, and doesn't make you look careless. The winners usually involve something outside your control — traffic, public transport, a sudden household drama — because nobody can hold you responsible for a broken-down train or a burst pipe. Keep it short, keep it calm, and don't over-explain. The more detail you pile on, the more it sounds rehearsed. Deliver it once, apologize briefly, and move on.

30 excuses for being late

For work

1. My train was delayed and the next one was canceled.
2. There was an accident on the motorway and traffic was at a standstill.
3. My car wouldn't start this morning — I had to wait for a jump.
4. The nursery/childminder rang and I had to sort something out first.
5. A delivery I had to sign for turned up right as I was leaving.
6. My alarm didn't go off — I think the phone update reset it.
7. The lift in my building was out, so I had to wait ages.
8. I had a plumber emergency — water everywhere, couldn't leave it.
9. My bus was diverted and dropped me miles from the stop.
10. I got a flat tyre on the way in.

For school

11. The bus didn't turn up and I had to wait for the next one.
12. My little brother/sister was sick and I had to help at home.

16. Our power went out overnight and everything reset — including my alarm.

For a date or plans

19. I lost track of time getting ready and want to look my best for you.
20. Parking near yours is a nightmare — I've been circling for ten minutes.
21. My phone died so I couldn't message — I got here as fast as I could.

25. I stopped to grab something for you and the queue was huge.

For traffic and transport

26. Signal failure held the whole line up.
27. There was a broken-down lorry blocking a lane.
28. The roads were flooded after last night's rain.
29. A diversion sent everyone down one narrow road.
30. Rush hour was heavier than usual — bumper to bumper the whole way.

What's the best excuse for being late to work?

The safest bet for work is a transport or traffic excuse, because it's completely outside your control and no reasonable boss will blame you for a canceled train or a motorway pile-up. "My train was delayed" and "there was an accident on the way in" are the classics for a reason — they're common enough to be instantly believable and impossible to pin on you. Send a quick message the moment you know you'll be late rather than explaining after you arrive; a heads-up reads as responsible, while a scramble at your desk reads as an afterthought. Keep the apology short and get straight to work.

What's a believable excuse for being late that isn't a lie?

The most convincing excuses are the honest ones you can lean into. If your alarm genuinely didn't go off, say so. If the traffic really was bad, that's your line. The trick is framing: acknowledge it briefly, apologize once, and show you've got a handle on the rest of the day. People are far more forgiving of a real, ordinary reason delivered with confidence than a wild story delivered nervously. If you're stuck for the right words in the moment, a plausible prompt can help you land it cleanly.

The bottom line

The best excuse for being late is short, believable, and something nobody can easily check — a delayed train, a dodgy alarm, a household emergency. Say it once, apologize, and carry on. Want a fresh, plausible reason every single time? Tap the Excuse Generator and roll one on demand.
