If you run a modified rig, my advise would be to find a local site dedicated to looking out for the little guy and that helps back up the little guy when he gets the crappy end of the stick by a law enforcement officer that interprets a law or act differently then another.
We have a pretty small wheeling population in my province (compared to California or something) but there's a ton of talk about guys getting screwed on our NB Offroad Club forum, and some of the members have started a 4x4 preservation site and deal directly with the officials to try and help rig owners that have been wronged.
It's not uncommon for guys to be pulled over with a legal rig, store-bought lifts, registration, insurance and provincial safety inspection in order, just because the cop sees something he 'thinks' that's unsafe. Several guys have had their rigs towed away and registration taken away. Often a new title is mailed back to them, a SALVAGE title.
Then they have to pay upwards of thousands of dollars to have their rig recertified by an engineer, who's not regulated and can do any type of inspection they want, for just about any price they decide to charge.
From what I understand, one poor bugger with a perfectly safe and legal TJ was stopped and was forced to have it re-certified. 2" commercially bought coil spacer lift and 31's.
The problem is the ways the laws are written, they leave a LOT open to interpretation.
I loved wheeling with the local jeep club, but it's not worth it if you're going to get hassled all the time. Frame rot made me get rid of my TJ, but the crap going on around here played a big part in my decision not to get another one.
If you love wheeling, I would suggest finding a good local group and get involved.... strength in numbers. if not, everyone will be blindsided when they start sliding stuff in and the public is caught with their pants down.
To give you an idea of the crap that we're dealing with in New Brunswick, have a read here:

Here's a link to a scan of the registered letter that guys are getting after being pulled over because a cop saw something unsafe on their rigs. To put it in perspective, one guy was stopped because his shocks were 'broken'. They were looking at the curved rubber dust boots. The cop that wrote him up didn't understand that the shocks were fine and the 'bent/broken' things he was looking at were just the accordion dust boots. Doesn't matter...once he's on the side of the road, it's all over.
Very important to note....here we have a mandatory Provincial Safety Inspection (aka MVI). Every year, every vehicle registered in New Brunswick is subjected to it. Steering, suspension, tires, brakes, ABS, body, lights, wipers, horn, parking brake, seat belts, air bags, etc.
These trucks are registered, are insured, and have valid MVI's. But yet the police can pull them over because their shock boots are crooked and their rigs become paperweights until they pay through the nose to have them re-certified by an engineer, and cough up big bucks to pay for that inspection.
If you love wheeling, do NOT sit on your rump and wait for this to take you by surprise. Start preparing, and get your ducks in a row now.
