@Mr Haematocrit is knowledgeable about carbon
Yes, it can suddenly fail if the crack is in the wrong place etc

Would you cycle with my Carbon Forks?

The best advise I could give is a professional inspection. The correct thing would be a xray as suggested by @vickster and Brunel University engineering department can assist with this, but its cost makes it prohibitive unless you have a high value or specialist fork.
You can put a light source in the fork to check for light escaping through any hairline fractures but I'm not convinced about this.
I have also seen a fork pressurized with air in a bucket of water as the air will escape as bubbles through any failures or cracks. The air pipe was attached and the top of the fork sealed with that strecthy wrap used by freight companies.
I would personally suggest buying a new fork if you want to be certain and have peace of mind, its a damn sight cheaper than dental bills.
Highly regarded carbon bike repairers such as CBS do not touch forks in general, they are really helpful however as such I would contact them for further advice.

It'll be the bike shop that organises the x ray presumably, you can't just rock up to your local A&E
Who was the other cyclist, do you know? They may have British cycling or CTC membership, if so you could look into claiming against them on their third party liability cover
Actually....
I have of course never abused the NHS (or MOD) equipment by X-Raying Snakes, Falcons, a horse, a ball of mud found to contain an early musket firing mechanism, a radio cassette for a School project, and a number of other bizarre items.
The trick is being able to recognise the results.
Look at this video, it shows clear linear markings around the join between metal and fork.
I assume that if something like this occurred in the middle of an otherwise clear area then it would be a fracture, but are these normal in this image, or is there a stress pint and those lines stress fractures?
