Is there a "10" code for "When will you reach your destination?"

actually there are as many ten code variations as there are police departments. Just use ETA, its shorter than either 10-84 or 10-26 or 10-77 etc etc, LOL!

 

10-8 arrived
10-26 location

 

the three I mentioned in my post are all variations of ETA for police. Wikipedia has a good chart that shows the several meanings for 10-codes
http://en.wikipedia.org/wiki/Ten-code
10-77 is the code I'm familiar with (I used to be a police dispatcher many years ago), but as I say, phonetically, its silly to use a 6 syllable code instead of the simpler 3 syllable "ETA".
Of course, there is always the shorter "WHERE Y'AT?"

 

I simply say whatever I need to in plain, clear, consise English. 10 codes are mainly for law enforcement, and people who think that truckers are still stuck in the 70's cb craze.

 

police, security, tow trucks (worked security and driving a towtuck in the past) all places I have seen and worked for was 97 arrive/meet and 98 was done/leaving the scene

 

10-Honey I'm home

 

As a former volunteer Firefighter and EMT I am quite familiar with the way things were done here. 10-23 was the code for arrived on scene, LEO's also used this code. 10-17 was enrouted, 10-8 was on duty, 10-7 was off duty and 10-6 was busy. 10-21 was phone call(give or receive).

 

Ours are:
10-8 Acknowledge page in service
10-76 Enroute
10-23 On scene
10-60 In area
10-24 Completed leaving scene
10-6 Busy

However, under the new rules we are moving away from 10 codes to sayings:
Available, enroute, basically used plain speech.
