Were the speed limits in your area set "legislatively," i.e., by political hacks? or by "traffic experts"? You won't know unless you ask! Preferably, you ask in advance, in writing, in a legal process typically called "discovery." Having the information before your court date helps you better prepare your case.

For example, a court has upheld cross-examining to determine if the witness is under pressure from the government concerning a pending charge, People v Makiel, 358 Ill App 3d 102; 294 Ill Dec 319; 830 NE2d 731, 745 (3 June 2005) lv app den 2005 Ill LEXIS 1703 (1 Dec 2005).
