Hi. Please help me to write a single expression to validate Canadian Quebec vehicle number
I have for each example one expression but i cant combine it. Can you help me? Thanks!

/^ [A-Z][0-9]{2}[\s][A-Z]{3}$/g; /*for A00 ABC*/
/^ [0-9]{3}[\s][A-Z]{3}$/g; /*for 000 ABC*/
/^ [A-Z]{3}[\s][0-9]{3}$/g; /*for ABC 000*/
/^ [0-9]{3}[A-Z][0-9]{3}$/g; /*for 000H000*/

Letters A, B, C, H may be replaced by other letters of the alphabet.
