If you mean "safely" as in "not flying off the road on bends" then yes.
We found on ours, the one time it played up and stopped working, it drove just like a normal car with anti-roll bars. and our journeys consisted of going up and down a steep mountain road with 44 bends in it 3 hairpins, a drop and rise of 360 metres, this journey taking 10 minutes.
Our normal trip into town.
TBH it was very little different.
When I got home, just for info, I tried to see what was wrong with it, took the fuse out, put it back in again and it has worked normally ever since.
As with ABS, it is stupid if anyone "relies" on it. Like a mate of mine did who then came off the road, or another van driver did who drove onto our side of the road and hit us. Just rememebr the E in ACE is Enhancement, not a replacement for anti roll bars.
There are peeps who have taken the whole system off and just drive with normal ARBs and if mine played up it is prolly what i would do.
